how are isotopes defined? forms of different elements that have the same number of neutrons in each atom forms of different elements that have the same number of protons in each atom forms of the same element that differ in the number of neutrons in each atom forms of the same element that differ in the number of protons in each atom

Answer:
forms of the same element that differ in the number of neutrons in each atom
