(a) Using de Broglie's hypothesis, explain with the help of a suitable diagram, Bohr's second postulate of quantization of energy levels in a hydrogen atom.
The ground state energy of hydrogen atom is -13.6 eV. What are the kinetic and potential energies of the electron in this state ?

Text Solution

Verified by Experts

(a) `lambda=(h)/(p)=(h)/(mv)`
`2pir = n lambda`
`2pir =n(h)/(mv)`
`rArr mvr=L =(nh)/(2pi)`

(b) Kinetic energy =13.6eV
Potential energy =-27.2 eV
