Answer:

Isotopes are versions of the same element. They have the same number of protons and electrons as the element but different mass numbers and number of neutrons.

one of two or more species of atoms of a chemical element with the same atomic number and position in the periodic table.

They are two or more atoms that have the same atomic number and position on the periodic table. For example; two or more forms of an element have the same number of protons but different numbers for neutrons.
