Question | Answer |
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. |
