Atoms (Adams?) continued

The amount of protons in the atomlocated on the top of the square from the periodic tableHydrogen has an atomic number of?

Atomic Number

Equal to the mass of the protons and neutrons (averaged)What is the mass of a proton, neutron, and

electron?Located on bottom of square

Atomic Mass

The total mass of a specific atom when the protons and neutrons are added

Mass Number

Elements that have the same number of protons (atomic number) but different amount of neutrons.

(This contributes to different atomic mass)
