Why are models used to represent atoms? O A. Models explain new evidence.
B. Models never change over time.
C. Atoms are too small to see.
O D. Models are completely accurate.

Explanation:

Models help us to understand systems and their properties. For example, an atomic model represents what the structure of an atom could look like, based on what we know about how atoms behave. It is not necessarily a true picture of the exact structure of an atom. Models are often simplified.
