POINTS: 1
QUESTION TYPE: Multiple Choice
HAS VARIABLES: False
OTHER: Macroscopic sample is a form of matter, which can be observed with the naked eye. A microscopic sample is too small to be seen with the unaided human eye, and a particulate is a type of matter that is too small to be seen with the human eye or an optical microscope.

- Why do chemists use models of atoms and molecules?
- Use of models is more convenient and less expensive than using photographs from microscopes.
- Matter at the particulate level is too small to be seen.
- Chemists follow the tradition established by Watson and Crick.
- High-powered electron microscopes create computerized models of atoms and molecules.
- To illustrate textbooks and scientific reports with more color than black-and-white photographs of the atoms
and molecules.
