Which particle is emitted when an atom OF 85Kr spontaneously decays?

An excited atom decays to it's ground state and emits a proton of green light if instead the atom decays to an intermediate state what could the light emitted be?
If an atom that emits a green proton when it decays to its ground state decays to an intermediate state instead it will emit a proton that is yellow/orange/red. The reason is that it will be a lower energy proton emitted and lower energy waves correspond to longer wavelengths like the ones that make up these colors.

What do you call waste that decays?
Waste that decays is called biodegradable waste. Dead plant material that has decayed (as in compost) is called humus.
Why an element call radioactive?
it is unstable and decays to another element

That's what an atom emits when it decays.
