Chemistry Vocabulary

matter anything that has mass and takes up space (has volume)
atom particle that makes up matter
element a substance made of atoms that are identical
temperature The measurement of the amount of kinetic (or motion) energy within a substance
melting point The temperature where a substance turns from a solid to a liquid
boiling point The temperature where a substance turns from a liquid to a gas
solubility The ability for a substance to dissolve
solute The substance that is being dissolved in a solution
solvent The substance that is dissolves the solute
phase change The process of a substance going from one phase of matter to another without changing any chemical properties
compound a substance formed when two or more chemical elements are chemically bonded together
Heterogenous Mixture a combination of two or more pure substances in which the original substances retain their chemical properties
Homogenous Mixture has uniform composition and properties throughout
Solution consists of a solute and a solvent
Atomic Mass average mass of atoms of an element, calculated using the relative abundance of isotopes in a naturally-occurring element
Atomic Number the number of protons in the nucleus of an atom, which determines the chemical properties of an element and its place in the periodic table
Periodic Table chemical elements arranged in order of atomic number, usually in rows, so that elements with similar atomic structure (and hence similar chemical properties) appear in vertical columns
evaporation process of a substance in a liquid state changing to a gaseous state due to an increase in temperature and/or pressure
condensation conversion of a substance (as water) from the vapor state to a denser liquid or solid state
Sublimation the transition of a substance directly from the solid to the gas phase without passing through the intermediate liquid phase
melting a physical process that results in the phase transition of a substance from a solid to a liquid
deposition direct solidification of a vapor by cooling; the reverse of sublimation
freezing process through which a substance changes from a liquid to a solid
volume quantity of three-dimensional space occupied by a liquid, solid, or gas
density the ratio between mass and volume or mass per unit volume
mass measure of the amount of matter in an object
weight name of the force exerted on an object due to the acceleration of gravity
ductility physical property of a material associated with the ability to be hammered thin or stretched into wire without breaking
maleability reason metals bend or dent when struck
conductivity a material's ability to conduct electricity
luster the way light interacts with the surface of a crystal, rock, or mineral
magnetism fundamental property of some materials (for example, iron) and electrical currents by which they are capable of exerting a force on magnets
