What is a main reason why the scientific model of atoms is considered a theory rather than a law? it has been proven as a fact. it has been changed over time. it predicts but does not explain. it has stayed the same for a long time.

The main reason why the scientific model of atoms is considered a theory rather than a law is because it has been changed over time.

Explanation;
