Question

In a Bohr's model of atom when an electron jumps from n = 1 to n = 3, how much energy will be emitted or absorbed (1erg = 10⁺ J) 

(1) 2.15 x 10^-11 erg

(2) 0.191 x 10^-10 erg

(3) 2.389 x 10^-12 erg

(4) 0.239 x 10^-10 erg

Answer 1

The correct option is (2).

Explanation:

According to Bohrs model

Since electron is going from n=1 to n=3 hence energy is absorbed.
