What Does A +2 Charge Mean? Q&A (2024)

1. A neutral particle is generally incorporated with an equal amount of charges which means the same number of protons and electrons.
2. In any chemical reaction if there is no decomposition of a compound or molecule occurs then they do not form any ions.
3. Ions are formed by the loss or gain of electrons, similarly, an atom loses or gains electrons in order to obtain any charge.
4. +2 charge indicates that any compound, molecule, or atom loses two electrons and becomes a cationic species.
5. -2 charge indicates that any compound, molecule, or atom loses two electrons and becomes an anionic species.
6. The example of a +2 charge is as follows: Barium$\left({\mathrm{Ba}}^{2+}\right)$, Cadmium$\left({\mathrm{Cd}}^{2+}\right)$, Lead$\left({\mathrm{Pb}}^{2+}\right)$, etc.
7. Barium loses its two electrons from the outermost shell to form $\mathbf{\left(}{\mathbf{Ba}}^{\mathbf{2}\mathbf{+}}\mathbf{\right)}$
8. The chemical reaction is as follows: $\mathrm{Ba}\to {\mathrm{Ba}}^{2+}+2{\mathrm{e}}^{-}$
