| Frequency | Number of waves passing per second |
| Velocity | All electromagnetic waves traveling at the same speed |
| Photons | Wave packet of Energy |
| Electron Orbital | Region of space around a nucleus of an atom within which there is 90% probability of finding an electron |
| Orbital | Specific Region of space inside a sublevel |
| Core electrons | electrons in inner energy level |
| valence electrons | electrons in outer sublevel |
| bond | the force that holds two or more atoms together and makes them function as a unit |
| bond energy | the energy required to break a given chemical bond |
| ionic bonds | the attraction between oppositly charged ions |
| ionic compound | a compound that results when a metal reacts with a nonmetal to form cations and anions |
| covalent bond | type of bond in which atoms share electrons |
| polar covalent | the electron are not shred equally because one atom attracts the shared electrons more than one atom |
| electronegativity | the tendency of an atom in a molecule to attract shared electrons to itself |
| dipole moment | property of a molecule in which the charge distribution can be represented by a center of positive charge and a center of negative charge |
| Lewis Structure | representation of a molecule or polyatomic ion showing how valence are arranged among the atoms in the molecule or ion |
| bond pair | a pair of electrons that are shared between two atoms forming a covalent or polar covalent bond |
| lone pair | electron pairs in a Lewis Structure that are not involved in bonding |
| single bond | a bond in which one pair of electrons is shared by two atoms |
| double bond | two pairs of electrons are shared by two atoms |
| triple bond | three pairs of electrons are shared by two atoms |
| resonance | a condition occurring when more than one valid Lewis structure can be written for a particular molecule |
| solution | homogenous mixture that does not settle |
| alloy | solid mixture with another solid |
| liquid solution | solid, liquid, or gas mixed in with another liquid |
| gaseous solution | solid, liquid, or gas mixed in with a gas |
| aqueous solution | liquid solution in which water is the main component |
| solvent | part present in the largest amount |
| solute | component present in the lesser amount |
| dilute | small amount of solute in mixture |
| concentrated | large amount of solute |
| unsaturated | less than the maximum amount |
| saturated | maximum amount of solute |
| supersaturated | more than the maximum amount of solute is dissolved in solution |
| soluability | maximum number of grams of solute per 100g or 100mL of water at a given temperature |
| molarity | concentration of solution involving moles |
| dilution | the process of adding the solvent to a solution to lower the concentration of solute |
| equivalents of an acid | amount of acid that can furnish one mole of hydrogen ions |
| equivalents of a base | amount of base that can furnish one mole of hydroxide ions |
| normality | number of equivalents per 1 L of solution |
| colligative property | property that is dependent only on the number of solute particles in solution |
| boiling point elevation | adding more solute to a solution will increase the boiling point of the solution |
| acid | proton donor (H+) |
| base | proton acceptor |
| hydronium ion | H3O ion formed when an acid is added to water |
| conjugate acid | substance formed when a proton is added to a base |
| conjugate base | remaining substance when a proton is lost from an acid |
| oxyacid | an acid in which the acidic hydrogen is attached to an oxygen atom |
| organic acid | acid with a carbon atom |
| amphoteric | substance that can act as both an acid and base |
