Isotopes of an element are atoms with the same number of protons, but a different number of neutrons. ... Having different numbers of neutrons in the nucleus will not affect the charge of the atom. Instead, different isotopes have different mass and have different tendencies to radioactively decay, or change over time.

What is the charge of an isotope?

Isotopes are atoms that have the same numbers of protons but different numbers of neutrons. An ion is an atom that has gained or lost electrons, so it now has more or fewer electrons than it does protons. So an ion has a negative or positive charge.

Is an isotope positive or negative?

Only about 118 different elements are known to exist. An atom is the smallest part of an element that can exist either alone or in combination with other atoms. Isotopes are atoms that have the same number of protons but different numbers of neutrons. An ion is an atom or molecule with a positive or negative charge.
