Question

• Arrange the following elements according to the increase in their electron affinity; (Si, P, S)?

Answer 1

Configuration of Si = 2,8,4

Configuration of P = 2,8,5

Configuration of S = 2,8,6

Si requires 4 more electrons to attain stable electronic configuration.

P requires 3 more electrons to attain stable electronic configuration.

S requires 2 more electrons to attain stable electronic configuration.

Thus, affinity of electrons in Si is maximum.

Arrangement : Si ➡ P ➡ S
