Question 507: Atoms & Nuclei

Question

Let T
1
and T
2
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 T
1
: T
2
is

Accepted Answer

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