Science SOL 5.4 - Matter Solid Nucleus Element Evaporation Condensation The state of matter that has definite shape and a definite volume The very tiny center of an atom A substance made up of only one kind of atom and cannot be broken down into another substance Occurs when particles escape from a nonboiling liquid and becomes a gas Changes a substance from a gas to a liquid Science SOL 5.4 - Matter Solvent The liquid in which a solute is dissolved to form a solution Boiling The temperature point at which a substance changes from a liquid to a gas Atom The smallest unit of an element; smallest building block of matter Solute Solubility The part in a solution that gets dissolved The ability of a substance to be dissolved Science SOL 5.4 - Matter Compound Periodic Table Mass A substance made of the atoms of two or more elements in a fixed ratio (different types of atoms) A table of elements in order of increasing atomic number and are grouped by similar properties The amount of matter in an object. Unlike weight, It is not based on gravity. Suspension A mixture in which one of the parts is a liquid and some particles do not dissolve Volume The amount of space that an object takes up Science SOL 5.4 - Matter Density Kilogram The concentration of matter in an object A larger unit used to measure mass (heavier objects); equal to 1,000 grams Matter Anything that has mass and takes up space Physical Properties that can be observed or measured without changing the substance into something else Freezing The temperature point at which a substance changes from a liquid to a solid Science SOL 5.4 - Matter Molecule Atomic Mass Gram Liquid Proton A particle made of two or more atoms linked together The measure of the amount of matter in one atom of an element. A small unit used to measure mass (lightweight objects) The state of matter that has a definite volume but no definite shape A subatomic particle with a positive charge Science SOL 5.4 - Matter Neutron Solution Atomic Number Mixture Electron A subatomic particle with no charge A mixture in which the composition is the same throughout; one or more substances dissolve in another substance The number of protons in one atom of an element A combination of two or more substances in which the atoms do not join together A subatomic particle with a negative charge Science SOL 5.4 - Matter Gas Chemical Symbol The state of matter that does not have a definite shape or volume The combination of one or two letters that represents the element Properties of Matter Color, taste, odor, shape, volume, texture, size, what it is made of Concentrate A solution that contains a large amount of solute Dilute A solution that contains a small amount of solute Science SOL 5.4 - Matter
