MCQ
The energy of a $2p $ orbital except hydrogen atom is
- ALess than that of $s{p^2}$ orbital
- ✓More than that of $2s$ orbital
- CEqual to that of $2s$ orbital
- DDouble that of $2s$ orbital
✓
Answer
Correct option: B.
More than that of $2s$ orbital
b
Atomic orbitals are filled always in the increasing order of their energies. $2s$ orbital is filled first than the $2 p$-orbital.
Atomic orbitals are filled always in the increasing order of their energies. $2s$ orbital is filled first than the $2 p$-orbital.
It means that $2 p$-orbital has more energy than the $2s$-orbital.
