Question

$\text{Electron gain enthalpy}\alpha \frac{1}{Atomicsize}$.

• A. True
• B. False

Answer 1

The correct option is A

True

In general electron gain enthalpy value decreases with an increase in atomic radius because the electrostatic force of attraction decreases between the electron being added and the atomic nucleus due to an increase of distance between them.
$\text{Electron gain enthalpy}\alpha \frac{1}{Atomicsize}$
