Be a chemist. Lol. Lessen waste, make chemicals more efficient, cure diseases... and stuff :)
Answer:
C. Scientists accepted the model at first but later rejected it.
Explanation:
Scientists accepted the model at first because it explained the hydrogen emission spectrum.
However, with the development of quantum mechanics, scientists had to modify the model (not reject it).
Electrons still had specific energies, but they no longer travelled in fixed orbits.
Instead, electrons had a probability of being found in a given region of space.
You would calculate them by dividing them and then multiplying to get the final answer
