Electronic Configurations of the d-Block Elements
- The electronic configuration of d-block elements is(n-1) d1–10 ns1–2. They have two incomplete outershells.
- Where (n–1) = Inner d orbitals having electrons from 1-10.
- ns = Outermost orbital may have one or two
- (n-1) d10 n s2 represents the electronic configurations of Zn, Cd and Hg.
- They exhibit variable valency that differ by units of one.
