»»»Calculate energy of electron which is moving in the orbit that has its radius 16 times the radius of first bohr Orbit for h- atom .

Answer 1

r= 16× i.e. n=4 and hence 13.6÷16

Answer 2

Answer: The energy of the 4th energy level is -0.85 eV.

Explanation:

The radius of the n-level is given by:

$r_n=5.29\times 10^{-11} m\times n^2$

$5.29\times 10^{-11} m\times n^2=16\times 5.29\times 10^{-11} m$

n = 4

Energy in nth level is given by :

$E_n=-\frac{13.6}{n^2} eV$

$E_4=-\frac{13.6}{4^2}=-0.85 eV$

The energy of the 4th energy level is -0.85 eV.
