Question

In a Bohr's model of an atom, when an electron jumps from $$n=1$$ to $$n=3$$, how much energy will be emitted or absorbed?

A
$$2.389\times {10}^{-12}$$ j
B
$$0.239\times {10}^{-10}$$ j
C
$$1.94\times {10}^{-10}$$ j
D
$$0.1936\times {10}^{-10}$$ j
Solution
Verified by Toppr

Correct option is A. $$2.389\times {10}^{-12}$$ j
$$\Delta E=(-R_H/n_f^2)-(-R_H/n_i^2)$$
$$n_i$$ & $$n_f$$ stands for initial and final orbit respectively
$$R_H$$=rydrberg's constant $$=2.18\times 10^{-18}$$
$$\Delta E=(-2.18\times 10^{-18}/3^2)-(-2.18\times 10^{-18}/1^2)$$
$$\Delta E=2.18\times 10^{-18}(1/3^2-1)$$
$$\Delta E=1.94\times 10^{-10} J$$
