Q. Which of the following statement is relation to the hydrogen atom is correct?
A) $3s$, $3p$ and $3d$-orbitals all have the same energy
B) $3s$ and $3p$-orbitals is lower energy than $3d$-orbital
C) $3p$-orbital is lower in energy than $3d$-orbital
D) $3s$-orbital is lower in energy than $3p$-orbital
Explanation
(a)
Hydrogen atom is in $1s^{1}$ and these 3$s$, 3$p$ and 3$d$-orbitals will have same energy w.r.t. 1$s$-orbital.
