Question

An electron is moving in an orbit of circumference 14.928 in Het Calculate
(a) Energy of electron in this orbit
(b) lonisation Energy of Het
(c) Separation energy​

Answer 1

Answer:

a number is the answer of this question

Answer 2

electron is moving in Bohr's fourth orbit. Its de-Broglie wavelength is λ. The circumference of the fourth orbit is

4λ

Note: For nth orbital, the circumference is nλ.

From Bohr's fourth postulate, the angular momentum mur is an integral multiple of

2π

h

mur=n×

2π

h

Circumference =2πr=n×

mu

h

=n×λ

As n=4

Circumference= 4λ
