unit 6 chemistry

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
oxyacid any acid that contains hydrogen and an oxyanion.
