From the New World Encyclopedia, "Technically, atomic mass is equal to the total mass of protons, neutrons, and electrons in the atom (when the atom is motionless), plus the mass contained in the binding energy of the atom's nucleus."
Mass number is the number of protons plus neutrons in an atom's nucleus. Mass number varies with individual isotopes due to the fact that atoms of the same element can have different numbers of neutrons.
Unified atomic mass unit
The atomic mass (or weight) of silver is 107.8682 amu (atomic mass units)
No, the atomic number is the amount of protons it has and the weight is its mass
Atomic mass - Atomic weight are the same , so look at your periodic table and below every element it will give you atomic mass.
The atomic mass of Krypton (Kr) is approximately 83.798 amu (atomic mass units).
