Question 472: Atoms & Nuclei

Question

If the electron in a hydrogen atom moves from ground state orbit to 5
th
orbit, then the potential energy of the electron

Accepted Answer

The potential energy of electron in hydrogen atom is given by
$$U =  - {1 \over {4\pi {\varepsilon _0}}}\,.\,{{{e^2}} \over r}$$
Hence, as r increases, potential energy will increase. (It will become less negative)
Alternatively, it is also given by
$$U =  - {{13.6} \over {{n^2}}}eV$$

Answer

is increased

Answer

is zero

Answer

is decreased

Answer

remains unchanged
