PHXII12:ATOMS

356613 Assertion :
The electron in the hydrogen atom passes from energy level \(n = 4\) to the \(n = 1\) level. The maximum number of photons that can be emitted are six.
Reason :
The photons are emitted when electrons make a transition from the higher energy state to the lower energy state.
