Thanks for asking us a question in Ask the Expert section of TopperLearning.com.
The EC of Mn+4 is : [Ar] 3d3 4s0
Half filled and fully filled orbitals are more stable. While splitting of 3d orbital, basically they are divided into two sets T2g (contains 3 orbitals ) and Eg (contains 2 orbitals). So in Mn+4 octahedral splitting (in which T2g is in lower energy state) takes place. So first we start filling T2g, and T2g contains 3 orbital so one electron is held in each orbital. So we get a half filled T2g because the half filled nature this oxidation state is stable.
