TEST BANK For Zumdahl, Chemistry 10th Edition
scanning tunneling microscope - ANSWER: Instrument used to "see" atoms.
Diatomic - ANSWER: two atom molecule.
Scientific Method - ANSWER: 1. Making observations ( collecting data)
2. Suggesting possible explanations (formulate hypothesis)
3. Do experiments to test the possible explanation (testing hypothesis)
Theory - ANSWER: a set of tested hypotheses that gives an overall explanation of
some natural phenomenon.
This is an interpretation, not a direct observation.
An attempt to explain "why".
