1.	Energy of the state S_(1) in units of the hydrogen atom ground state energy is
Answer» 0.75 1.5 2.25 4.5 Solution :For `S_(1)` state of `Li^(2+)`, n = 2 and Z = 3. `THEREFORE" "` Energy of the state `S_(1)` in the units of hydrogen atom ground state energy is : `E=E_(H)xx(Z^(2))/(n^(2))=E_(H)xx(3^(2))/(2^(2))=9/4E_(H)=2.25xxE_(H)`
