Atomic Mass is the number of protons in an atom's nucleus. Since all atoms are, in their natural state, neutral, there are the same number of electrons as protons. Thus, the atomic mass tells you both the number of electrons and protons an atom has.
No, this answer is incorrect. Atomic mass is the number of protons plus neutrons. Only the number of protons is equal to the number of electrons in a neutral atom; so knowing the atomic mass doesn't tell you the number of electrons, because you don't know the combination of protons and neutrons that were added together to get the atomic mass.

∙ 14y agoThe mass is the total number of subatomic particles: protons, electrons, and neutrons. The reason it is often a decimal is that the number on the table is the average for the most common isotopes. Isotopes are atoms of an element with different numbers of neutrons.
