A charged atom or molecule is known as an ion. Because there are more electrons than protons in the atom or molecule, it is charged.
An atom or molecule is said to be an ion if one or more of its valence electrons have been gained or lost, giving it a net positive or negative electrical charge. In other terms, a chemical species has an unbalanced ratio of protons (positively charged particles) to electrons (negatively charged particles).
An atom or collection of atoms that is classified as an ion has more electrons than protons. That implies that an atom becomes an ion when it acquires or loses an electron. Ion examples include the following: H+,Na+,Ca2+,F−,O2−
