Ionic charge: When the atom loses or gains one or more electrons, the electric charge is generated (and an ion is formed). This electric charge generated on the ion is known as Ionic charge.
When atoms gain electron/s, the negatively charged ion is formed, and when the atoms lose electron/s, the positively charged ion is formed.
List of elements with their common ionic charges are mentioned below.
Elements with multiple ionic charges are also mentioned in this table.
