Question | Answer |
Anything that has mass and takes up space. | Matter |
The amount of matter in something. | Mass |
The amount of space something occupies. | Volume |
Firm and stable in shape, not a liquid or a fluid. | Solid |
State of matter with definite volume but no shape. | Liquid |
Random groups of atoms that can take up any spaced container. | Gas |
A property used to characterize materials in reactions that change their identity. | Chemical Property |
Any property used to characterize matter and energy and their interactions. | Physical Property |
Smallest unit of matter. | Atom |
Number of protons in an atom of a given element | Atomic Number |
Number of protons plus the number of neutrons in an atom. | Atomic Mass |
Center of the atom that has the protons and neutrons (heaviest part of the atom). | Nucleus |
Positive subatomic particle in the nucleus. | Proton |
Neutral subatomic particle in the nucleus | Neutron |
Negative subatomic particle that is around the outside of the nucleus. | Electron |
Ability to be flattened into a sheet; bendable, | Malleability |
Ability to be stretched into a wire. | Ductility |
Ability to react with another substance. | Reactivity |
