Question

Statement 1:The $3p$-orbital has higher energy level than $3s$ in $H{e}^{+}$ ion.
Statement 2: The energy of an orbital depends upon $n$ and $l$

• A. If both Statement $1$ and Statement $2$ are true and the Statement $2$ is the correct explanation of the Statement $1$.
• B. If both Statement $1$ and Statement $2$ are true but Statement $2$ is not the correct explanation of the Statement $1$.
• C. If Statement $1$ is true but Statement $2$ is false.
• D. If Statement $1$ is false but Statement $2$ is true

Answer 1

Answer: (D)

Higher is the value of $(n+l)$ more is the energy level of orbital. For one electron systems energy of $3s=3p$.
