The atomic number is just the number of protons in the nucleus of an atom of any given element. Looking on the Periodic Table, we can see that oxygen, for example, has 8 protons, whilst calcium and tin have 20 and 50 protons respectively.
The number of protons is also equal to the number of electrons in an uncharged atom.
(i.e) Chromium(Cr), 24.
Boron(B), 5.
Potassium(K), 19.

Why is platinum give the atomic number 78?
Platinum is a non metal element. Atomic number of it is 78.
What information does the atomic number give on the periodic table?
The number of protons an element has.
What info can be found in a square on the periodic table?
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 an element. On many printed periodic tables we can have atomic number, atomic weight and some other properties like melting and boiling points may also be included.the atomic number and the atomic mass. the atomic number tells you how many neutrons and electrons are in the atom, and the atomic mass tells you the combined amount of protons and neutrons and that element. there is also the symbol of the element, which is the symbol for it's name, and most tables provide the name of the elements.Most basic periodic tables contain four pieces of information for each element: the element's name, symbol, atomic number, and atomic mass. For example, the first element would have an "H", the name Hydrogen, a number 1, and a number 1.0079. H is hydrogen's symbol. The 1 is hydrogen's atomic number, which is the number of protons its nucleus. The 1.0079 is hydrogen's atomic mass.More detailed periodic tables may include number of valence electrons, electron configuration, electronegativity, ionization energy, and other properties.It varies depending on which table you use. A general table will give you the atomic number, element symbol, and atomic mass.The periodic table contains several pieces of information about each element. The element's square on the table includes its atomic symbol, atomic number, and atomic weight.Each square represents the name of the element, the atomic number, and the atomic mass of the element.
What does the atomic mass minus atomic number tell you about the element?
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.
What is the average atomic mass of phosphorus?
why would I know this sit would not give me the answer :[
What do Protons give to an atom?
Number of protons = the atomic number of the element
Why is platinum give the atomic number 78?
Platinum is a non metal element. Atomic number of it is 78.
Any element can always be identified by its?
The atomic number of an element is equal to the number of protons in the nucleus of that element; it will identify the element. The number of neutrons of a given element may be different as the element may have a number of isotopes.
What information does the atomic number give on the periodic table?
The number of protons an element has.
What give the most information about what kind of element an atom is?
the atomic number <<< apex : )

What is the symbol for silicon-28?
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.
What has 50 protons and 66 neutrons?
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 same element with the same number of protons but a different number of neutrons. Often 1-4 numbers off its original atomic mass number.
How can you calculate the number of neutrons N in an atom?
equal to number of protons

What information does the atomic number of an element give you?
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
