Class 12 Chemistry D and F Block Elements Electronic Configurations of the d-Block Elements

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.
