In order to come up with our modern-day atomic model, scientists added knowledge to pre-existing discoveries. Which of the following shows the correct sequence of
scientists?

Earnest Rutherford was JJ Thomson’s student. He disproved Thomson’s plum pudding model. So Rutherford comes after Thomson. Dalton is first because you should be aware of Daltons atomic theory on the atom. He was one of the first people to actually make a theory about atoms in that type of detail. Bohr came last. I forgot what Bohr’s model was, but you can do a quick google search if you want.

So your answer is B, the second one
