Chapter 8 Covalent Bonding

a chemical bond that results from the sharing of valence electrons

• covalent bond

• pi bond

• sigma bond

• coordinate covalent bond

a model that uses electron-dot structures to show how electrons are arranged in molecules. Pairs of dots or lines represent bonding pairs

• resonance

• Lewis structure

• structural formula

• molecule

condition that occurs when more than one valid Lewis structure exists for the same molecule

• structural formula

• resonance

• VSPER model

• molecule

a process in which atomic orbitals are mixed to form new, identical hybrid orbitals

• VSPER model

• molecule

• lewis structure

• hybridization

a molecule consisting of two atoms

• diatomic molecule

• single covalent bond

• double covalent bond

• triple covalent bond

a pair of valence electrons that is not shared between atoms

• unshared pair

• molecular orbital

• double covalent bond

• polar covalent bond

a bond angle of 109.5° that results when a central atom forms four bonds directed toward the center of a regular tetrahedron

• tetrahedral angle

• right angle

• acute angle

• tutankhamun angle

a covalent bond in which electrons are shared equally by the two atoms

• nonpolar covalent bond

• polar covalent bond

• molecular bond

• ionic bond

a molecule in which one side of the molecule is slightly negative and the opposite side is slightly positive

• polar molecule

• nonpolar molecule

• single covalent bond

• diatomic molecule

What are the three types of strong chemical bonds?

• Metallic, Ionic and Covalent
• Metallic, Atomic and Electronic
• Ionic, Atomic and Nucelonic
• Covalent, Metallic and Electronic
