Question

if the electron of a hydrogen atom is present in its first orbit ,the total energy of the electron is

Answer 1

I hope you help !!

If the total energy of an electron revolving in orbit is E than; P.E=2E & K.E=-E

Total energy of electron in first Bohr orbit of hydrogen is -13.6ev.

Kinetic energy of electron in the first Bohr orbit of hydrogen is, K.E=-(-13.6ev)=13.6ev ans..

Answer 2

Explanation:

answer is option c) e^2/2r
