Verified step by step guidance

Understand the definitions of the given terms: A molecule is two or more atoms bonded together without necessarily having a charge.

An isotope refers to atoms of the same element that have different numbers of neutrons, affecting atomic mass but not charge.

An element is a pure substance consisting of only one type of atom, defined by its number of protons.

An ion is an atom or group of atoms that has gained or lost electrons, resulting in a net positive or negative charge.

Since the question asks for a charged atom or group of atoms, the correct term is 'ion'.
