It has a d4 configuration. While acting as a reducing agent, it gets oxidized to Cr 3+ (electronic configuration, d3). This d3 configuration can be written as 3t 2g configuration, which is a more stable configuration. In the case of Mn 3+ (d4), it acts as an oxidizing agent and gets reduced to Mn 2+ (d5).

"WebThere is a difference in the trend of ionisation enthalpy from boron to beryllium in the second period. The ionisation enthalpy of boron should, in theory, be greater than that of beryllium, but this is not the case. The reason for this is that beryllium contains fully filled subshells, and it also has a penetrating effect. " - Ionisation enthalpy of mn is lower than cr+
