Find the maximum value (n+l+m) for unpaired electrons in second excited state of chlorine ._(17)Cl .

Number of unpaired electrons in sulphur is

According to V.B.T., atoms of element form bond only to pair up their unpaired electrons present in ground state or excited state. This pairing of unpaired electron will take place by overlapping of orbitals each one having one unpaired electron with opposite spin. Which of the following orbital cannot form delta -bond ?

How many unpaired electrons are present in N_2^+ ?
