covalent bond | chemical bond that results from the sharing of valence electrons |
molecule | forms when 2 or more atoms covalently bond and is lower in potential energy than its constituent atoms |
Lewis structure | a model that uses electron-dot structures to show how electrons are arranged in molecules. Pairs of dots or lines represent bonding pairs. |
sigma bond | single covalent bond formed when an electron pair is shared by direct overlap of bonding orbitals |
pi bond | bond that is formed when parallel orbitals overlap to share electrons |
endothermic reaction | chemical reaction or process in which a greater amount of energy is required to break existing bonds in the reactants than is released when new bonds from in product molecules |
exothermic reaction | chemical reaction or process in which more energy is released than is required to break bonds in the initial reactants |
