Answer 1

can someone help me answer this question. thanks

Answer 2

The original atomic model held that atoms were a "pudding" of positive and negative particles.

This was disproven by Rutherford's Gold Foil experiment, which indicated the presence of a small, dense nucleus. At this point, though, the behavior of electrons was still somewhat unclear.

Niels Bohr originally postulated that electrons orbited atoms in predictable ways, much like planets did. However, we now know that they actually form a "cloud", making it difficult to pinpoint the exact locations of individual electrons.

I can't remember any particular dates, however, so you'll probably need to check those out for yourself.
