Bohr Model (Hydrogen-like Atom)
Watch an electron drop between energy levels of a hydrogen-like atom and see the photon it gives off — pick the levels and the nuclear charge, and read the wavelength, energy and which series the line belongs to.
What you can adjust
- Nuclear charge (Z)
- 1 – 3
- Initial level (n_i)
- 2 – 6
- Final level (n_f)
- 1 – 5
- Animation duration
- 1 – 4 s
How many protons the nucleus carries. Z=1 is hydrogen; Z=2 is singly-ionized helium (He+); Z=3 is doubly-ionized lithium (Li2+). A higher Z pulls the electron in tighter, so every transition emits a more energetic (shorter-wavelength) photon.
The energy level the electron starts on before it drops. Must be higher than the final level.
The energy level the electron drops to, emitting a photon. n_f=1 is the Lyman series, n_f=2 is Balmer (the only series with lines in visible light), n_f=3 is Paschen, and so on.
How long the clip runs — the electron orbits on the initial level, drops, then orbits on the final level.
