Give reason for why the ground state outermost electronic configuration of sillcon's

Text Solution

Verified by Experts

The correct Answer is:
A
Hund's rule of maximum multiplicity is used for the filing of electron in degenrate orbitals gtDuring the filling of electrons in degenerate orbital of a subshell , puring does not takes plane till orbital gets one electron with parallel spin .The electron nucleus interction is improved when the spins are parallel
