I believe the answer is "Bohr's model explains the chemical behavior of all atoms."
This compound should be classified as a suspension fluid. This happens when a fluid is denser than another fluid.
The answer is most likely nonmetals. :)
Mixture: matter than is composed of two or more substances that can be separated by physical means (ex; let's say you have a jar of red and blue marbles. this is a mixture. You can separate the colors with your hands (physical means.))
Compound: a substance in which two or more atoms are chemically combined in a fixed proportion (ex: water is a compound that consists of the element hydrogen and the element oxygen).
