Chemistry
Among the period 2 elements, the element which has the highest electron affinity is:
- Lithium
- Carbon
- Chlorine
- Fluorine
Answer
Fluorine
Reason — In period 2 elements (Li, Be, B, C, N, O, F, Ne), Fluorine (F) has the highest electron affinity. As, electron affinity increases across a period due to decreasing atomic radius and increasing nuclear charge. Atoms more readily accept electrons to complete their octet.
