Question | Answer |
Covalent bond | The chemical bond that results from the sharing of valence electrons |
Molecule | is formed when two or more atoms bond covalently |
Lewis structure | use electrons-dot diagrams to show how electrons are arranged in molecules |
Sigma bond | Single covalent bonds |
Pi bond | is formed when parallel orbitals overlap to share electrons |
endothermic | reactions occur when a greater amount of energy is required to break the existing bonds in the reactants than is released when the new bonds form in the product molecules. |
exothermic | reactions occur when more energy is released forming new bonds than is required to break bonds in the initial reactants. |
Oxyacid | Any acid that contains hydrogen and an oxyanion |
structural formula | uses letter symbols and bonds to show relative positions of atoms |
resonance | is a condition that occurs when more than one valid Lewis structure can be written for a molecule or ion. |
coordinate covalent bond | when one atom donates a pair of electrons to be shared with an atom or ion that needs two electrons to become stable |
VSEPR model | Valence Shell Electron Pair Repulsion Model |
Hybridization | a process in which atomic orbitals are mixed to form new, identical hybrid orbitals. |
Polar covalent | unequal Sharing results |
