Protons | The positively charged part of an atom |
Neutron | The neutrally charged part of the atom |
Proton | The positivley charged part of an atom |
Atomic Number | The number of protons an atom has |
Isotopes | An atom that has the same number of protons but a different number of neutrons. |
Ion | When the number of electrons vary |
Atomic weight | (percent → decimal) (atomic weight) + (percent → decimal) (atomic weight) + . . . = average atomic weight |
