A Li++ ion and hydrogen ion are both in the second excited state. If lH and lLi are their respective electronic angular momenta and EH and ELi their respective energies, then –
A
lH > lLiand |EH| > |ELi|
B
lH = lLi and |EH| < |ELi|
C
lH = lLi and |EH| > |ELi|
D
lH < lLi and |EH| < |ELi|
Answer
lH = lLi and |EH| < |ELi|
