| a bond that results from the sharing of valence electrons | ||
| chemical reaction in which a greater amount of energy is required to break the existing bonds in reactants than is released when the new bonds form in product molecules | ||
| a chemical reaction in which more energy is released that is required to break bonds in the initial reaction | ||
| a model that uses electron-dot structures to show how electrons are arranged in molecules | ||
| forms when two or more atoms covalently bond; usually includes two or more nonmetals | ||
| a type of bond that forms when electrons are not shared equally | ||
| a molecular model that uses symbols and bonds to show relative positions of atoms | ||
| model based on an arrangement that minimizes the repulsion of shared and unshared pairs of electrons around the central atom | ||
| a mixture of elements that has metallic properties | ||
| the force that holds two atoms together | ||
| the electrons involved in metallic bonding that are free to move easily from one atom to the next throughout the metal and are not attached to a particular atom | ||
| the simplest ratio of ions represented in an ionic compound | ||
| the electrostatic force that holds oppositely charged particles together; usually a nonmetal paired with a metal | ||
| the attraction of a metallic cation for delocalized electrons | ||
| ion formed from only one atom | ||
| the positive or negative charge of a monatomic ion | ||
| an ion made up of two or more atoms bonded together that acts as a single unit with a net charge | ||
| States that atoms lose, gain or share electrons in order to acquire a full set of eight valence electrons | ||
| States that atoms like hydrogen and helium only need two valence electrons to be stable | ||
| condition that occurs when more than one valid Lewis structure exists for the same molecule | ||
| an element that can make bonds with more than 8 electrons, able to do so because they all have empty d orbitals |
