2. when atoms are heated so that they emit light, what characteristic of their light

allows you to tell one atom from another?

The color of the light.

Explanation:

When an atom is heated, its electrons are excited and they jump to higher energy levels. The electrons will return to their normal energy level, and by doing this, they will emit a photon of energy, which is in the form of light. The color of the light depends on the difference of energy of the two levels, and because of that is different for each element.
