Question

a) Calculate the energy associated with the first orbit of ${He}^{+}$. What is the radius of this orbit?
b) What is the lowest value of n that allows ${}^{\prime }{g}^{\prime }$ orbitals to exist?

Answer 1

(a) calculate the energy associated with the first orbit of $H{e}^{+}$

$E=-13.6\frac{z^2}{n^2}$

$=-13.6\times \frac{2^2}{1^2}=54.4ev$

Radius of orbit $r=529\times \frac{n^2}{z}nm$

$=529\times \frac{12}{2}$

$=264.5nm$

(b) lower value of $n=5$

$spdfg$
