Statement $1$ and Statement $2$ are both true,and Statement $2$ is the correct explanation of Statement $1$.

Vedclass · Answer

(A) Statement $1$ is true because,in a hydrogen-like atom,the energy of an orbital depends only on the principal quantum number $(n)$,given by the formula $E_n = -R_H 	imes (Z^2 / n^2)$.Statement $2$ is also true because the principal quantum number $(n)$ defines the shell and determines the average distance of the electron from the nucleus.Since the energy level of the electron is directly related to its distance from the nucleus (as defined by the shell $n$),Statement $2$ provides the physical basis for Statement $1$.

Statement $1$: The energy of an electron is determined by the principal quantum number.
Statement $2$: The principal quantum number $(n)$ indicates the distance of the electron from the nucleus.
