Detailed explanation-1: -ion, any atom or group of atoms that bears one or more positive or negative electrical charges. Positively charged ions are called cations; negatively charged ions, anions.

Detailed explanation-2: -An ion is a charged atom or molecule. It is charged because the number of electrons do not equal the number of protons in the atom or molecule. An atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.

Detailed explanation-3: -An atom that has a charge is called an ion. An ion can be positive or negative depending on whether it has more protons than electrons or more electrons than protons. This is because protons carry a positive charge while electrons carry a negative charge. Neutral atoms will have an equal number of protons and neutrons.

Detailed explanation-4: -An ion is produced as a result of gain or loss of electrons by an atom.

Detailed explanation-5: -A radical is an atom or a group of atoms of the same or different elements that acts as a single unit and has a positive or negative charge.
