Question

Write true or false. Correct the false statement.

An atom that gains one or more electrons to form a negative ion is called a cation.

• A. True
• B. False

Answer 1

The correct option is B False

• An ion is formed when an atom losses or gains electrons.
• Ions are of two types - cation (positive ion) and anion (Negative ion)
• The positively charged ion or the ion formed by losing the electrons is known as a cation. For example - ${\mathrm{Na}}^{+}$ ion is formed when a sodium atom loses one electron, ${\mathrm{Ca}}^{+2}$ ion is formed when calcium loses two electrons, etc.
• While the negatively charged ion or the ion formed by gaining the electrons is known as an anion. For example - ${\mathrm{Cl}}^{-}$ ion is formed when a chlorine atom gains one electron, ${\mathrm{O}}^{-2}$ loses two electrons, etc.

Hence, the given statement is false.

Correct statement - An atom that gains one or more electrons to form a negative ion is called an anion.
