Question

In group 6, Mo(6) and W(6) are found to be more stable than Cr(6). Why ?

Answer 1

Answer:

your answer

In group 6, Mo(VI) and W(VI) are found to be more stable than Cr(VI) because. This easier availability of d and s electron occurs as higher energy d and s orbital like 4d,5d,3s and 4s allow the orbital to loss electron easily and form stable higher oxidation state.
