Answer:

B: The colors of light emitted from heated atoms had very specific energies.

Explanation:

In Thompson's model of an atom the atom is said to be constituted of electrons which are surrounded by a haze of positive charge in order to balance the electrons' negative charges. It is also called plum prodding model because of negatively charged plums which are surrounded by the positively charged pudding.

Now, as the electrons move from higher to lower energy levels a photon which is a particle of light will be given off.

Thus, the correct answer is option B
