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.
It tells you the average amount of protons and neutrons within the nucleus of an atom. In other words, atomic mass - atomic number (protons)= the number of neutrons within the nucleus.
it tells us that the number is equal to the number of protons plus the number of nuetrons in the nucleus of an atom
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.

The atomic mass number tells how many protons and neutrons are in a nucleus.
Atomic Number tells you how many protons and electrons there are in a neutral atom.
atomic mass is the answer
The Atomic Mass number tells the atomic mass of an element. The mass is calculated as the mass of all the protons and neutrons in the center of an atom.
The atomic mass (rounded to the nearest whole number) is the number of nucleons - i.e. protons+neutrons. The atomic number is just the number of protons. So the difference between the two (mass minus number) tells you the number of neutrons.

- It tells you what number it is on the periodic table of elements.- The number of protons in the nucleus (centre of the atom)- And the number of elecrons orbiting around the atomthe 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.

atomic weight goes up faster
In Nuclear Physics, A stands for atomic mass number. Atomic number is the number of protons and neutrons present in the nucleus of a given atom. Basically it tells us about the mass of the atom, as nucleons are the only sub-atomic particles which have mass. Nucleons mean neutrons and protons.
It tells you how many protons are in the element. For example if the atomic number is 5 then the protons of the element is 5.
The atomic number is the number of a chemical element in the periodic table of Mendeleev; the atomic number is equal to the number of protons and electrons. The atomic mass is the mass of an atom expressed in relative atomic mass units.
