Answer:
False
Step-by-step explanation:
Cation is formed from an atom by the loss of electrons.
For e.g., Na loses an electron to form Na+
Na – e → Na⁺
The electron configuration of Na: 1s² 2s² 2p⁶ 3s¹
The electron configuration of Na⁺: 1s² 2s² 2p⁶
In the formation of Na⁺ there is a loss of electron from the 3s orbital. As a result the size of the Na⁺ ion is less than Na atom.
