 What experiment requires the emission of energy by an atom be quantized?



   thanks

Burn some table salt, you'll notice that light only emits in the yellow frequency. Instead of at all frequencies giving a rainbow or white light effect.

Albeit this is not the best experiment.

Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3. Forum Supports LaTex

I think all cases should be quantitised due to the fact that all electrons in atoms can only be promoted to and demoted to fixed energy levels within the atom.
