Where is all the mass located in an atom?
The nucleus. Protons + Neutrons= Mass
What is the only area of the atom that deflected light when beams were shot through the atom?
Is n=1, n=2, or n=3 located closer to the nucleus?

How does an element produce light when heated?
The electrons absorb energy as they heat up and jump energy levels. When they become unstable and drop back down towards the nucleus, photons are emitted producing light.
