Identify the element from following having six unpaired electrons in observed electronic configuration?

Options

  1. ACu
  2. BZn
  3. CCr
  4. DTi

Correct answer

C. Cr

Step-by-step solution

Chromium (Cr): Expected electronic configuration: [ Ar ] 3 ~d ^4 4 ~s ^2 Observed electronic configuration: [ Ar ] 3 ~d ^5 4 ~s ^1 Hence, number of unpaired electrons in observed electronic configuration is 6 .
