Detailed explanation-1: -An ion is an atom or molecule which has lost or gained one or more electrons, and carries a net electric charge. If the result is an atom with more electrons than protons, the ion is negatively charged. If there are fewer electrons than protons the ion is positively charged.

Detailed explanation-2: -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-3: -Ions consisting of only a single atom are termed atomic or monatomic ions, while two or more atoms form molecular ions or polyatomic ions.

Detailed explanation-4: -When one or more electrons is stripped away from an atom, it becomes positively charged. Some atoms can attract additional electrons so they become negatively charged. Atoms which are not electrically neutral are called ions. One can collect electric charge by transferring electrons.
