Question

Which of the following is not a correct statement regarding the energies of orbitals?

• A. The lower the value of $(n+l)$ for an orbital, lower is its energy
• B. Electrons in the same subshell have equal energy
• C. Energy of $s$-orbital is lower than the $p$-orbital and that of $p$-orbital is lower than the $d$-orbital
• D. If two orbitals have same value for $(n+l)$, the orbital with higher value of $n$ will have lower energy

Answer 1

Answer: (D)

If two orbitals have same value for $(n+l)$, the orbital with lower value of $n$ will have lower energy.
