Energy levels Flashcards
1
Q
Excitation
A
Providing enough energy for an electron to move up to a shell further from the nucleus (up to a higher energy level
2
Q
Dexcitation
A
An electron loses it’s energy from excitation and emits it as a photon and falls back to an inner shell
3
Q
How are electrons excited with photons?
A
The electrons absorb photons which have the exact energy to move it to a higher energy
4
Q
Why do some substances fluoresce?
A
Elements absorb UV light and then, through de-excitation elements emit visible photons. The
