Energylevel In atoms Flashcards
1
Q
excitation using photons?
A
electron in the atom can absorb a photon and move to an outer shell where space is, only if energy of photon is exactly equal to the gain in the electrons energy
2
Q
deexcitation?
A
vacancy is filled by another electron, filling the space the excited electron left. this electron emits a photon
3
Q
energy of emitted photon?
A
hf = E1 - E2
4
Q
stopping potential
A
ek max / charge
