Give an example of atomic number and mass number in a element?
Example: oxygen has the atomic number 8.
Natural isotopes of oxygen have the following mass numbers:
- 16O: 16
- 17O: 17
- 18O: 18
If you know the atomic number of an element what information does it give you about neutral atoms of that element?
the atomic number represents its "weight". for example oxygen has an atomic number of 8 and it has 8 protons, 8 electrons and 8 neutrons ( the neutral part)
You can get the number of neutrons of an element by taking the number of protons, the number of electrons, or the atomic number of the element (seeing as they are all the same number) and subtract that number from the atomic mass. This will give you the number of neutrons of an element. EXAMPLE: THE ELEMENT -BERYLLIUM (Be) Atomic number/Proton number/Electron number =4 Mass number= 9 To find neutron number: Mass number- Atomic number/Proton… Read More
The number of protons/electrons in an atom of that element.
Platinum is a non metal element. Atomic number of it is 78.
Number of protons = the atomic number of the element
The element is Tin. This can be worked out by simply finding the element with the proton number (or atomic number) of 50. You can double check this by working out the atomic mass number by adding 50 + 66 to give 116. The atomic mass number may not always be the same with elements (as seen with this example) because what you're referring to is an isotope. An isotope is an atom of the… Read More
- take your average mass and round it, then take your atomic number and subtract it by your average mass. This will give you you atomic mass of an element. -
The number of protons an element has.
Atomic mass minus atomic number will give you the average number of neutrons in that element. Bear in mind that atomic mass is based on the actual weight of that element, which is the result of whatever isotopes appear in nature; it is rarely based on only a single isotope.
The number of protons is the same as the atomic number. For example... For the element Boron the atomic number is 5, so this would also be the number of Protons in this element. The number of electrons is the same as the number of protons. For example... For the element Boron the number of protons is 5, because that is the atomic number, so it is also thr number of electrons. This is so… Read More
You can find the Atomic Number, Atomic Mass, The Element symbol and Name and sometimes, the numbers of the electrons in each shell. (for a Bohr model) Also element symbol can be called atomic symbol. The information is the atomic number, also stands for how many electrons and protons there are in that element, also it tells what the atomic abbreviation is and the real name. Each square on the periodic table gives information about… Read More
Elements can be defined based on the singularity of substances that make up its composition, the number of protons, the number of electrons and the atomic weight. Elements cannot be broken down into simpler substances. The number of protons and electrons will be unique for each element. The atomic weight is determined by the number of protons and neutrons.
28/14 Si Its the number they give you which is the atomic mass of the isotope over the atomic number and the symbol of the element.
For any element, this is answered in the same way. The mass number is the number of protons plus the number of neutrons, in this case 50. The atomic number is the number of protons. Subtract the atomic number from the mass number to give the number of neutrons. For any element, this is answered in the same way. The mass number is the number of protons plus the number of neutrons, in this case… Read More
The atomic number tells you how many protons are in one atom of that element. It also tells you the number of neutrons in one atom.
Im pretty sure it gives you the proton number,i could be wrong
The atomic number is how many protons there are, and since the number of protons is equal to the number of electrons, it is also the number of electrons. You can take the number of protons away from the atomic weight (overall weight) which will give you the number of neutrons. (Electrons don't weigh anything in the atomic weight so you don't need to subtract this as well). Hope this helps :D
Look up the name on the periodic table and subtract the atomic number from the mass number (which is protons and neutrons). That will give you the number of neutrons.
How can you find the number of protons and neutrons in an atom of an element from the atomic number and the mass?
Protons = Atomic Number, Electrons = Protons, Neutrons = Atomic Mass - Protons. Electons give a negative charge Protons give a positive charge In general, the atom would have the same amount of protons and electons, so it is neutral.
The periodic table give the atomic numbers and the atomic weights of chemical elements.
They are not equal. To work this out you will need to look at a periodic table (or to know the atomic number and the mass number). Minus the atomic number from the mass number to give your answer. (the atomic number is the number above an element square in the periodic table and the mass number is the number below)
To find the total number of electrons in an element, first you need to look up the element's atomic number. That number tells you how many protons are in the element. Then, look up the net charge of the element. The number of protons subtracted by the elements net charge will give you the number of its electrons.
There is no easy way to tell the number of neutrons an element might have, other then to look it up somewhere. Some references will give you the mass number, which is the total number of protons & neutrons. Also, most elements belong to a family of "isotopes" ,which is the same element with different numbers of neutrons. Usually the one you find in a reference is the one most abundantly found in nature. For… Read More
protons will tell the atomic number (8) the sum of protons and neutrons will give the mass number of the element
well you look at the periodic table of elements. the atomic number equals the number of protons. Then subtract the number of protons from the atomic mass (both protons and nuetrons have atomic mass units of 1 and electrons equal 0). That will give you the number of nuetrons.
I think this either a trick question or a mistyping. An element always has the same number of protons, i.e. the same atomic number. What can vary are the number of NEUTRONS which give rise ti different isotopes of the element.
The number of neutrons for any given element varies, depending on the isotopes. Search the Wikipedia, or Google, for "Isotopes of Zirconium" for the isotopes of this particular element. The list of isotopes will give you the atomic mass (protons + neutrons) for the different isotopes; subtract the atomic number (which is the number of protons) to get the number of neutrons for each isotope.
Isotopes of an element have nuclei with the same number of protons (the same atomic number) but different numbers of neutrons. Therefore, isotopes have different mass numbers, which give the total number of nucleons-the number of protons plus neutrons. Many, if not all, elements have isotopes. Most are unstable, i.e. radioactive, due to interactions involving the weak force. IN SHORT:Isotopes have the same atomic number but different atomic mass. For example: Carbon-12, for instance, has… Read More
The frequencies of light emitted by an element separate into discrete lines to give the atomic emission spectrum of the element.
The atomic number of an atom indicates the number of protons that the atom has. All atoms contain protons, neutrons and electrons. (The exception is hydrogen which has only one proton and one electron). It is the number of protons that defines the element. So, helium with an atomic number of 2 will always have 2 protons. Normally, the atom will have the same number of electrons as protons but there are many instances where… Read More
It is not a formula, it is the atomic number and the mass number. The atomic number is the number of protons. The mass number is the weight of a single atom of the element and also the number of protons and neutrons. The number of neutrons can be found by taking the proton number from the atomic number. If you are talking about moles and titration then change the question and I will give… Read More
A periodic table should be useful here, there even is a link provided for you below. One glance at the forty second element on the table should give you your answer. the element is molybdenum.
The question is too vague to give any clear answer to - the number of protons in any element is the same as the atomic number, so in the case of Li, there are 3 protons.
Nothing is following. Also, just take a look at the periodic table of elements (which, if you don't have one, can be easily looked up on google) which will give you the atomic number of each element. Every element has exactly as many protons as its atomic number, and in their neutral state (not ionized) they also have exactly that number of electrons.
A shiny metallic element with the chemical symbol Fe. It has the atomic number 26 and the relative atomic mass 56. It can form an orangey-brown oxide commonly called rust
Actually, atomic is not a root word, but an adjective that is used to give description to other words. Example: atomic clock The root word for atomic is atom, which is used as 'the basic unit of a chemical element.' It comes from the Latin word atomos which basically means 'can not be divided.'
How much that element weighs
Atomic mass is the average mass of all isotopes of a given element.
The number of protons in a nucleus depends on the element. Hydrogen has 1 proton, helium has 2 protons, and lithium has 3. All elements have different numbers of protons in the nucleus. If you look on a periodic table, each element has an atomic number. That number is the number of protons there is in the nucleus of an atom of that element. Give or take a proton away, and the atom becomes tha… Read More
Edwin Mac Millan , Philip H. Abelson, 1940: Neptunium (atomic number 93).
The mass number of an atom is the sum of the neutrons and protons. If you know which element it is, you can look up the atomic number - which will give you the number of protons, then just add the number of neutrons to get the mass number.
All atoms in a particular element have same electronic configuration which is a characteristic for that element. Best way to understand this is to look at the periodic table which shows how all the elements are arranged in particular order. All atoms of a given element will have the same number of protons. It is the number of protons that give an atom its elemental identity. Its atomic number is taken from the proton count… Read More
The number of electrons in a mole of any substance would be Avogadro's number times its atomic number (if an element) or times the sum of the atomic numbers of its molecule (if a compound) So, since the atomic number of Al is 13, the number of electrons is (6 X 10^23) X 13 = 78 X 10^23. Give or take a few.
The vertical columns are called groups or families. The horizontal rows are called periods. A basic periodic table will give the name, chemical symbol, atomic number, and atomic weight of each element.
Atomic mass - Atomic weight are the same , so look at your periodic table and below every element it will give you atomic mass.
We make atomic number by number of protons in a atom. PVC is not single atom. We cant give it a atomic number.
The atomic mass of an element is the total number of protons and neutrons in its nucleus. It is usually not expressed as a whole number because it is the average of all of the element's known isotopes, which have different quantities of neutrons. It is different from the atomic number, which is the quantity of protons only and is always a whole number. Electrons are not counted because the mass of an electron is… Read More
Depends on the atom. The atomic number will give you the number of protons. The atomic weight will give you approximately the number of protons and neutrons combined.
The nucleus is where all the mass of the atom is to be found and every nucleus is made of Protons and Neutrons which have about the same mass. Together these therefore give the atom its Mass Number. Thus if you know the Mass Number you know how many Protons and Neutrons the atom contains. If you are then told how many Neutrons there are, a simple subtraction of this number from the Mass Number… Read More
The atomic number of helium is one. And also the atomic number appears on my screen when I talk, or say a number.
