Which element from following has highest melting point?

Options

  1. ACr
  2. BV
  3. CMn
  4. DFe

Correct answer

A. Cr

Step-by-step solution

The melting point of transition metals depends on the strength of metallic bonding, which is directly proportional to the number of unpaired electrons available for bonding. The electronic configurations of the given elements are: V : [ Ar ] 3d^3 4s^2 ( 3 unpaired electrons) Cr : [ Ar ] 3d^5 4s^1 ( 6 unpaired electrons) Mn : [ Ar ] 3d^5 4s^2 ( 5 unpaired electrons) Fe : [ Ar ] 3d^6 4s^2 ( 4 unpaired electrons) Chromium (Cr) has the maximum number of unpaired electrons ( 6 ), which leads to the strongest metallic bo
