have different numbers of electrons
have different numbers of protons
have different numbers of neutrons
have different atomic numbers
react differently with other atoms

Answer 1

The atoms of different phosphorus isotopes have different numbers of neutrons.

Isotopes of an element have the same number of protons (and thus the same atomic number) but differ in the number of neutrons, resulting in different atomic masses.
