Question 260: Atoms & Nuclei

Question

As an electron makes a transition from an excited state to the ground state of a hydrogen - like atom/ion :

Accepted Answer

$$U =  - K{{z{e^2}} \over r};\,\,T.E = {k \over 2}{{ze^2} \over r}$$
$$K.E = {k \over 2}{{z{e^2}} \over r}.$$ Here $$r$$ decreases

Answer

kinetic energy decreases, potential energy increases but total energy remains same

Answer

kinetic energy and total energy decrease but potential energy increases

Answer
