$E_n 	ext{ for } A^{(+z-1)} = Z^2 	imes E_n 	ext{ for } H$

Vedclass · Answer

(A) The energy of an electron in a hydrogen-like species is given by the formula: $E_n = -13.6 	imes \frac{Z^2}{n^2} 	ext{ eV}$.For a hydrogen atom,$Z = 1$,so $E_n(H) = -13.6 	imes \frac{1^2}{n^2} = -13.6 	imes \frac{1}{n^2}$.For the species $A^{(+z-1)}$,the atomic number is $Z$. Thus,$E_n(A^{(+z-1)}) = -13.6 	imes \frac{Z^2}{n^2}$.Comparing the two,we get $E_n(A^{(+z-1)}) = Z^2 	imes E_n(H)$.

The energy level for $A^{(+z-1)}$ is given by which of the following expressions?
