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 atomic mass tell you?
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.
What does the atomic mass tell us?
it tells us that the number is equal to the number of protons plus the number of nuetrons in the nucleus of an atom
What is the relationship btw atomic mass and atomic mass number?
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.

Why is the atomic mass number not a whole number?
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.
What number tells the mass of the nucleus of an atom?
The atomic mass number is the mass of the nucleus in atomic mass units.
What is the atomic mass number?
The atomic mass number tells how many protons and neutrons are in a nucleus.
What do the atomic number and atomic mass tell you about an atom?
Atomic number tells the number of protons and electrons, but i don't remember for atomic mass.
What do the atomic number and mass number tell about an atom?
Atomic number tells the number of protons and electrons, but i don't remember for Atomic Mass.
What do the atomic number and mass number tell you about an atom?
Atomic number tells the number of protons and electrons, but i don't remember for Atomic Mass.
Does an element's mass number tells the number of protons in its nucleus?
Close; Mass # is the number of protons + the number of neutrons.
What is the atoms mass number?
The Atomic Mass number tells how many protons and neutrons are in a nucleus.
How is atomic number better than atomic mass?
Atomic Number tells you how many protons and electrons there are in a neutral atom.
Tells you the number of atoms in each element?
atomic mass is the answer
What is the number called that tells how heavy an element is?
atomic mass
What does atomic mass number tell us?
Type your answer here..The Atomic Mass Unit tells us that ,How heavy a substance as compare to the other.
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.
