| Question | Answer |
|---|---|
| The substance of witch any physical object consist or is compressed. | Matter |
| having three dimensions as a geometrical body or figure. | Solid |
| composed of molecules that move freely among themselves but do not tend to separate like those of gases. | Liquid |
| a body of coherent matter, usually of indefinite shape and often of considerable size. | Mass |
| a substances possessing perfect molecular mobility and the property of indefinite expansion, as apposed to a solid or liquid. | Gas |
| a collection of written or printed sheets bound together and constituting a book. | Volume |
| any property used to characterize matter and energy and their interactions. | physical property |
| a property or characteristic of a substance that is observed during the reaction in witch the chemical composition or identity of the substance is changed. | chemical 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 |
| horizontal rows on periodic table | period |
| vertical columns on periodic table | groups |
| temperature where solid turns to liquid | melting point |
| temperature where liquid turns to gas | boiling point |
| shiny, good conductors, malleable, ductility | metal |
| like both metal and non-metal, shiny, malleable, semi-conductors | metalloid |
| poor conductors, mostly gases, dull | non-metal |
