Atomic Structure and isotopes

Isotope- Form of an atom with the same number of protons and electrons but a different number of neutrons and therefore different masses

Proton- mass=1, charge=1

Neutron- mass=1, charge=0

Electron- mass= 1/1836, charge=-1

Atomic number- Number of protons (electron number is equal)
