Question 564: Atoms & Nuclei

Question

The ground state energy of hydrogen atom is $$-$$ 13.6 eV. When its electron is in the first excited state, its excitation energy is

Accepted Answer

E
n
= $$ - {{13.6} \over {{n^2}}}$$
E
1
= -13.6 eV
E
2
= $$ - {{13.6} \over {{2^2}}}$$ = -3.4 eV
$$ 	herefore $$ $$\Delta $$E = ( Ã¢ÂÂ 3.4) Ã¢ÂÂ ( Ã¢ÂÂ 13.6) = 10.2 eV.
