CHE-Ch 8 Vocab (Covalent Bonds)

Front

A reaction requiring more energy to break bonds than is released when new bonds form.

Back

endothermic reaction

Front

Valence shell electron pair repulsion model minimizes electron repulsion around the central atom.

Back

VSEPR model

Front

Forms when one atom donates a pair of electrons to another atom or ion needing two electrons for stability.

Back

coordinate covalent bond

Front

A single covalent bond formed by direct overlap of bonding orbitals.

Back

sigma bond

Front

Process of mixing atomic orbitals to create identical hybrid orbitals.

Back

hybridization

Front

Condition with multiple valid Lewis structures for a molecule.

Back

resonance

Front

Forms when two or more atoms covalently bond and has lower potential energy than its atoms.

Back

molecule

Front

Bond formed by overlapping parallel orbitals to share electrons.

Back

pi bond

Front

A reaction releasing more energy than needed to break initial bonds.

Back

exothermic reaction

Front

Model using electron-dot structures to show electron arrangement in molecules with dots/lines for bonding pairs.

Back

Lewis structure
