Covalent Bonds

Objectives

• Distinguish between the differences of covalent/molecular and ionic compounds.
• Write Lewis Dot Structures of covalent compounds and polyatomic ions.
• Describe how electrons are shared to form covalent bonds.
• Demonstrate how electron dot structures represent shared electrons.
• Describe how atoms form double and triple bonds

Vocabulary: covalent bond - molecule - unshared pair - molecular formula - single covalent bond - double covalent bond - triple covalent bond

Objectives

• Describe how VSEPR theory helps predict the shapes of molecules
• Learn about the five basic shapes, linear, bent, triganol planar, pyramidal, tetrahedral

Vocabulary: molecular orbitals - tetrahedral angle - VSEPR theory

Objectives

• Describe how electronegativity values determine the distribution of charge in a polar molecule
• Learn how to determine if a molecule is polar or nonpolar overall

Vocabulary: nonpolar bond - polar bond - polar molecule - dipole
