The relative atomic weight or standard atomic weight (not mass) of a chemical element is the ratio between the average mass of the atoms of this element to 1/12 from the Atomic Mass of carbon-12.
What else can I help you with?
What atom has the mass number of 25?
Knowing the nuclear charge of an element is important as it will tell you what kind of reactions you can expect. The element with the nuclear charge of 25 is manganese.
How do you find the chemical element of an atom?
If you know how many protons the atom has, then that can tell you what element from the periodic table is classifying the atom.
What does the atomic weight of an element tell us about it?
The atomic number tells us the number of protons in the nucleus of an atom. The atomic mass tells us the sum of the protons and neutrons in a nucleus.The atomic weight (not mass) of a chemical element is the ratio between the average mass of the atoms of this element to 1/12 from the atomic mass of carbon-12.The atomic mass is a term applied only to specific isotopes; the unit is the same as above. Is a value denoting the total mass of all the protons, neutrons, and electrons in an isotope.The mass number tells us the number (the sum) of protons and neutrons in the nucleus of an atom.The atomic number, on the other hand, tells us how many protons are in the nucleus of an atom.IUPAC publish periodically tables of atomic weights - the last edition is from 2009-2010.For the atomic masses of isotopes the last published edition is The AME 2003 atomic mass evaluation, edited by Audi, Wapstra and Thibault.
What does the number of protons in an atom also tell you?
The number of protons in the nucleus of an atom tell you which element you are dealing with. It is the number of protons in an atomic nucleus that determines the elemental identity. Only that. The atomic number of an element is the number of protons you will find in the nucleus of every atom of that element, regardless of the number of neutrons or electrons involved.
How can the number of neutrons in an atom be determined?
1. Locate the element on the periodic table.2. Find the element’s atomic number (which is the same as the number of protons)3. Find the element’s atomic weight.4. Round off the atomic weight to the nearest whole number to find the atomic mass.5. Subtract the atomic number from the atomic mass (The numbers after the decimal point represent the usually very small mass of the electrons in the atom.)
What does the atomic mass tell you about the atom?
The Atomic Mass of an element tells you the average mass of an atom in the element.
What is relative atomic mass and how it is related with gram?
when atomic mass of an element expressed in gram atom is called gram atom mass . and formula is number of gram atom=given mass (in gram) by atomic mass ( in gram )
What can the atomic mass tell you about an atom?
the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.
How do scienctist tell the difference between two isotope of the same element?
Isotopes of the same element are determined based off the number of neutrons the atom has which is directed related to the atomic mass of the element( the more neutrons the greater the mass of that atom). Because you can not change the number of protons in an atom without changing the element, scientist differentiate isotopes based off the atomic mass of the isotope.
What information does an atom mass give you?
The mass of an atom gives you an idea of how heavy it is in relation to other atoms. It is the total mass of the protons, neutrons, and electrons in the atom. The atomic mass is typically measured in atomic mass units (amu).
What the atomic mass tell the total number of?
The Atomic Mass of an element tells you what the mass of one mole (6.022 x 1023 atoms) of the element is. It sort of tells you the number of protons & neutrons in the atom, but that is not necessarily precise.
What does the atomic mass tell you about a atom?
The mass.If you also know the element number you can figure out the number of neutrons (provided its an isotopic mass rather than an average mass).
What does the protons and neutrons tell you about the oxygen atom?
protons will tell the atomic number (8) the sum of protons and neutrons will give the mass number of the element
What does the atomic mass tell you about the element and it's protons and neutrons?
The atomic mass of an element represents the average mass of its isotopes, taking into account their abundance. It is the sum of the protons and neutrons in the nucleus of an atom. By subtracting the atomic number (number of protons) from the atomic mass, you can determine the number of neutrons in the nucleus.
How do you tell the number of neutrons in an element?
Subtract the atom number from the mass number to get the neutron. Mass number is the sum of neutrons and electrons. Atom number is the number of electrons. the number of electrons is equivalent to the number of protons.
How do you tell figure out the atomic mass?
Atomic mass is the number of protons + the number of neutrons in the nucleus of an atom. On the periodic table, the average atomic mass of an element will the be number at the bottom of each box.
What does an element's mass number tell us?
An element's mass number tells us the total number of protons and neutrons in its nucleus. It helps to determine the element's atomic mass and differentiate it from other isotopes of the same element.
