Question

The electron affinity of fluorine is ______ than that of chlorine.

Answer 1

The electron affinity of fluorine is less than that of chlorine.

Explanation:

Although fluorine is more electronegative, its electron affinity is less than chlorine’s. This is because the small size of fluorine leads to high electron density, which makes it harder to accommodate an extra electron. Hence, less energy is released when fluorine gains an electron compared to chlorine.
