Question

Write the symbols of Oxide ion

Answer 1

Ions: An ion is a charged particle that carries a positive by losing electrons and carries a negative charge by the gain of electrons.

• A positively charged ion is called a cation and a negatively charged ion is called an anion.
• An oxide ion is an anion that is formed by the gain of two electrons so, it carries two units of negative charge.

Therefore Oxide ion can be represented as ${\mathrm{O}}^{-2}$
