Among the following, the energy of 2s orbital is lowest in:
a) |
Li |
b) |
Li |
c) |
H |
d) |
Na |
Among the following, the energy of 2s orbital is lowest in:
a) |
Li |
b) |
Li |
c) |
H |
d) |
Na |
As the value of Z (atomic number) increases, energy of orbitals decreases (becomes more –ve value) order of energy of 2s orbital is
H > Li > Na > K
