Question

light is emitted from atoms when electrons go to higher energy levels. this is false i know but why?

Answer 1

It TAKES energy to move the negative electron farther away from the positive protons (higher energy level, more potential energy). When a system requires energy, it means you must GIVE it light, heat, etc.

Now, if an electron is moved to a lower energy level (closer to the protons), energy is released, and that energy ends up in the form of light.
