Several models of atoms were mentioned in the lesson this week. Plum pudding, planetary and quantum mechanical. Which reason below explains why there are different atom models?

There are different atomic models due to the fact that with advancement in technology and research, the atom began to open up. More scientists began to formulate models that would completely unify the different observations about the atom.

From the different model of atom, noticeable progressions could be observed in terms of sophistication and what they entail. As more details of the atoms were revealed, the need to modify the model becomes important.
