Question

Which electron transition would result in the emission

of energy?
A) 3s to 4s
B) 3p to 4p
C) 3s to 3p
D) 4p to 4s
HELP PLEASE!!

Answer 1

When the electron transits from an excited state to its lower energy state, it will gice off the same amound of energy needed to raise to that level. This emitted energy is a photon.

The answer is C, 3s to 3p.
