Question

why sulphur shows multiple vacancy?​

Answer 1

Answer:

Explanation:

Phosphorous and Sulphur both have electrons that have entered the 3rd shell s, p, d orbitals. ... It is similar in Sulphur. Thus, elements from third period onwards have multiple valency as they can form one number of bonds in non excited state and another number of bonds in excited state due to presence of d orbital.

Answer 2

Sulphur has electronic configuration [Ne]3s2 3p4 so it has vacant 3 d orbitals available to expand its octet
