When electrons in an atom become 'excited,' what typically occurs?
A
Electrons are ejected from the nucleus.
B
Electrons combine to form neutrons.
C
Electrons absorb energy and move to higher energy levels.
D
Electrons lose energy and move to lower energy levels.
Verified step by step guidance1
Understand that electrons in an atom occupy specific energy levels or shells around the nucleus under normal conditions.
When electrons become 'excited,' they absorb energy from an external source such as heat or light.
This absorbed energy allows electrons to move from their original lower energy level (ground state) to a higher energy level (excited state).
Note that electrons do not get ejected from the nucleus, nor do they combine to form neutrons; these processes are unrelated to electron excitation.
Remember that after excitation, electrons often return to their original lower energy levels by releasing energy, but the key event during excitation is the absorption of energy and movement to higher energy levels.
