Vedclass · Answer

(A) For a hydrogen-like atom,the energy of the $n^{th}$ orbit is given by $E_n = -13.6 	imes \frac{Z^2}{n^2} 	ext{ eV}$.As $n$ increases,$E_n$ becomes less negative,meaning $E_1 Therefore,the statement $E_1 > E_2 > E_3$ is incorrect.Potential energy $(PE)$ is given by $PE_n = -27.2 	imes \frac{Z^2}{n^2} 	ext{ eV}$,so $PE_1 Kinetic energy $(KE)$ is given by $KE_n = 13.6 	imes \frac{Z^2}{n^2} 	ext{ eV}$,so $KE_1 > KE_2 > KE_3$ is correct.

Which of the following orders is $NOT$ correct for the $1^{st}$,$2^{nd}$,and $3^{rd}$ orbits of a hydrogen-like atom?
