Bohr's Model for Hydrogen Atom

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 ?

Easy

A

$2 .839 \times 10^{- 12} ergs$
B

$0 .239 \times 10^{- 10} ergs$
C

$2 .15 \times 10^{- 11} ergs$
D

$0 .1936 \times 10^{- 10} ergs$

Solution

Energy of electron when n = 1
Energy of electron when n = 3

$- 21.7 \times 10^{- 12} \times \frac{8}{9} = 0.1928 \times 10^{- 10} ergs$
