Question

Write the symbol of Aluminium 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 Aluminium ion is a Cation that is formed by the loss of three electrons so, it carries three units of positive charge.

Therefore Aluminium ion can be represented as ${\mathrm{Al}}^{+3}$
