Chemical bonds The attractive force that holds two atoms together. May be either ionic or covalent.
The octet rule In forming compounds, atoms of elements lose, gain or share electrons in such a way as to produce a noble-gas electron configuration for each of the atoms involved.
Ionic bond model Electron transfer between two or more atoms
Polyatomic ions An ion formed from a group of atoms (held together by covalent bonds) through loss or gain of electrons
Covalent bond model Electron sharing between two or more atoms
VSEPR theory A set of procedures for predicting the molecular geometry of a molecule using the information contained in the molecule’s Lewis structure.
Electronegativity A measure of the relative attraction that an atom has for the shared electrons in a bond.
Bond polarity A measure of the degree of inequality in the sharing of electrons between two atoms in a chemical bond.
Collision theory A set of statements that give the conditions necessary for a chemical reactions to occur.
Chemical equilibrium The state in which forward and reverse chemical reactions occur simultaneously at the same rate.
Combination /Decomposition reactions A chemical reaction in which a single product in produced from two or more reactants and the opposite reaction.
Combustion reaction A chemical reaction between a substance and oxygen that proceeds with the evolution of heat and light.
Replacement reactions A chemical reaction in which an atom replaces an atom from another compound or two compounds exchange parts to become different substances.
Redox reaction A chemical reaction in which there is a transfer of electrons from one reactant to another reactant
Thermic reactions A chemical reaction in which energy is either used or released as the reaction occurs.
