An excited atoms has the electronic configuration `1s^(2)2s^(2)2p3d` being in the state with the greatest possible total angular momentum, Find the magnetic moment of the atom in that state.

Explanation

To get the greatest possible angular momentum we must have `S=S_(max)=1`
`L=L_(max)=1+2=3` and`J=L+S=4`
Then `g=1+(4xx5+1xx2-3xx4)/(2xx4xx5)=1+(10)/(40)=(5)/(4)`
and `mu=(5)/(4)sqrt(4xx5)mu_(B)=(5sqrt(5))/(2)mu_(B)`
