Covalent Bonding and Molecular Compounds

What is a covalent bond?

Bond formed when two nonmetals share electrons

What is a molecular compound?

Compound formed by covalently bonded nonmetals

How are molecular compounds formed

When two or more nonmetals share valenc electrons to achieve stable electron config

What are oxidation numbers in covalent compounds?

Hypothetical charges

Do molecular compounds form ions?

no, they share electrons

Key differences between ionic and covalent bonds?

Ionic: transfer of electrons, metal + non-metal.

Covalent: sharing of electrons, non-metal + non-metal.

Properties of molecular compounds?

Lower melting/boiling points, often gases or liquids, poor conductors.
