Chemistry Exam 4

Bond Angle

The angle between two bonds in the VSEPR model of a molecule.

Bond energy

The energy required to break a given bond.

Bond Length

The distance between the nuclei of the two atoms connected by a bond

Formal Charge

The charge assigned to an atom in an molecule or polyatomic ion

Hybridization

a mixing of orbitals

Pi bond

a type of covalent bond that has side to side overlap of orbitals

Resonance

a phenomenon in which a molecule can be represented by two or more valid Lewis structures. These structures contribute to the overall hybrid structure, affecting the molecule's stability and properties.

Sigma Bond

a typr of covalent bond that has end to end orbitals

lattice energy

the energy change occurring when separated gaseous ions are packed together to form an ionic solid

metallic bonding

the attraction between a metal nuclei and valence electrons

nonpolar covalent bond

electrons are shared equally in a covalent bond.

polar covalent bond

electrons are shared equally in a covalent bond
