| Question | Answer |
|---|---|
| Electron | negatively-charged particle that exists in an electron cloud formation around an atom's nucleus |
| positive ion | proton |
| negative ion | neutron |
| ionic bond | attraction that holds oppositely charges ions close together |
| covalent bond | chemical bond formed when atoms share electrons |
| subscript | number of atoms in a molecule |
| molecule | neutral particle formed when atoms share electrons |
| formula | combination of chemical symbols and number that indicates which elements and how many atoms of each element are present in a molecule |
| symbol | represents an element |
| compound | pure substance that contains two or more elements |
| polar molecule | having two oppositely charged ends |
| solute | substance that dissolves and seems to disappear in another substance |
| solvent | substance that dissolves the solute |
| chemical equation | shorthand form for writing what reactants were used and what products are formed in a chemical reaction; sometimes whether energy is produced or absorbed |
| condensation | the process of changing from a gas to a liquid |
| vaporization | the process by which a liquid changes into a gas |
| metals | element that is malleable, ductile, a good conductor of electricity, and generally has a shiny or metallic luster |
| nonmetals | element that is usually a gas or brittle solid at room temperature and is a poor conductor of heat and electricity |
| metalloids | element that shares some properties with both metals and nonmetals |
| isotopes | two ro more atoms of the same element that have different numbers of neutrons in their nuclei |
| matter | anything that takes up space and has mass |
| heterogeneous mixture | type of mixture where the substances are not evenly mixed |
| homogeneous mixture | type of mixture where two or more substances are evenly mixed on a molecular level but are not bonded together |
| reactant | substance that exists before a chemical reaction begins |
| product | substance that forms as a result of a chemical reaction |
| newton | unit of measurement of force |
| element | substance that cannot be broken down into simpler substances |
| amorphous solid | solids that have particles in a random arrangement |
| physical change | change in which the form or appearance of matter change, but not its composition |
| chemical change | change in which the composition of a substance changes |
| transition elements | elements in groups 3-12 in the periodic table, all of which are metals |
| representative elements | elements in groups 1 and 2 and 13-18 in the periodic table that include metals, metalloids, and nonmetals |
| catalyst | substance that speeds up a chemical reaction but is not used up itself or permanently changed |
| thermal energy | energy that all objects have that increases as the object's temperature increases; the sum of the kinetic and potential energy of the particles in a material. |
| temperature | a measure of the average value of the kinetic energy of the particles in a material |
| heat | thermal energy transferred from a warmer object to a cooler object |
| kinetic energy | energy an object has due to its motion |
