Find the number of elements which have less value of first electron affinity as compared to P atom.

N, C, O, S, Si

Answer:

Solution:

Phosphorus (P) has lower EA due to half-filled stability (3p³)

Among given: N, C, O, S, Si
Only Nitrogen (N) has even lower EA (strong half-filled stability)

So, number of elements = 1
