Five possible transitions for a hydrogen atom are listed below: Select whether the atom gains or loses energy for each transition.

$$Loses$$Gains$$ ni $=4$; nf $=6$

$$Loses$$Gains$$ ni $=7$; nf $=4$

$$Loses$$Gains$$ ni $=2$; nf $=6$

$$Loses$$Gains$$ ni $=7$; nf $=3$

$$Loses$$Gains$$ ni $=3$; nf $=5$

$$Tries $0/10$

Find the transition where the atom gains the most energy. How much energy does the atom gain?

$$Tries $0/10$

Find the transition which will emit the shortest wavelength photon. What is the energy of the photon of this transition?
