The total energy of an electron in an at...

The total energy of an electron in an atom in an orbit is `-3.4eV`. Its kinetic and potential energies are, respectively:

A

`-3.4eV,-3.4eV`

B

`-3.4eV,-6.8eV`

C

`3.4eV,-6.8eV`

D

`3.4eV,3.4eV`

Text Solution

Verified by Experts

In Bohr's model of H atom
`:.K.E. =|TE|=(|U|)/2`
`T.E.=K.E.+U`
`:.K.E.=3.4eV`
`U=-6.8eV`
