Question 550: Atoms & Nuclei

Question

Let T1 and T2 be the energy of an electron in the first and second excited states of hydrogen atoms, respectively. According to the Bohr's model of an atom, the ratio T1 : T2 is

Accepted Answer

$${E_n} = {{{E_0}} \over {{n^2}}}$$, For first excited state $$\Rightarrow$$ n = 2
For second excited state $$\Rightarrow$$ n = 3
$$ \Rightarrow {{{T_1}} \over {{T_2}}} = {{{{{E_0}} \over 4}} \over {{{{E_0}} \over 9}}} = {9 \over 4}$$
