WebCr2 + is strongly reducing in nature. 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). Webconfiguration of Cr+ is d5, therefore, ionisation enthalpy of Mn+ is lower than Cr+. In the same way, Fe2+ has d6 configuration and Mn2+ has 3d5 configuration. Hence, ionisation enthalpy of Fe2+2+. 2+ + 10 10 Sc Ti V Cr Mn Fe Co Ni Cu Zn therapist day to day duties
