Atomic Mass

Atomic Mass:

• It is the mass of the protons, electrons, and neutrons in one single atom. 
• Unusually it is done by AMUs or atomic mass units. 
• Atomic mass is normally said to be the mass of an atom which is the mass of one isotope. 
• An isotope is defined by dictionary.com as "any of two or more forms of a chemical element, having the same number of protons in the nucleus, or the same atomic number, but having different numbers of neutrons in the nucleus, or different atomic weights." 
• Some people say that atomic mass is similar to relative atomic mass, average atomic mass, and atomic weight but that isn't correct. 
• Relative atomic mass is very close to atomic weight and now it is replacing atomic weight
• John Dalton was basically the first person to determine the atomic weight of atoms
