Question

Choose the correct word given within brackets, complete the following sentences.

A positively charged ion is called _______. (anion/cation)

Answer 1

• Cations are the positively charged species that are formed by the loss of electrons by any element or molecule.
• Example, Sodium ion (${\mathrm{Na}}^{+}$) is the cation formed by the loss of one electron (${\mathrm{e}}^{-}$) from the element Sodium ($\mathrm{Na}$).

$\mathrm{Na}\to {\mathrm{Na}}^{+}+{\mathrm{e}}^{-}$

• Hence, a positively charged ion is called a cation.
