Question

an atom’s emission of light with a specific amount of energy confirms that
atoms must have a dense central mass surrounded by electrons at a distance,
electrons emit and absorb energy based on their position around the nucleus,
electrons can only be found within predicted areas surrounding the nucleus,
atoms are made of positive and negative charges.

Explanation:

When an atom emits light of a specific energy, it is because electrons transition between energy - levels. Electrons emit and absorb energy based on their position around the nucleus. This is related to the quantization of energy levels in an atom.

Answer:

electrons emit and absorb energy based on their position around the nucleus
