Covalent Bonds and Properties of Simple Molecules

Vocabulary flashcards covering covalent bonding, types of covalent bonds, and properties of simple molecules from Chapters 2.5 to 3.1.

Covalent bond

A bond that forms when two atoms share a pair of electrons, occurring only between non-metals.

Molecule

A particle formed by atoms joined together by covalent bonds.

Noble gas structure

A full outer electron shell achieved by each atom through the sharing of electrons.

Single covalent bond

A bond formed by one shared pair of electrons, with examples including $H_2$, $HCl$, $H_2O$, $CH_4$, and $NH_3$.

Double covalent bond

A bond formed by two shared pairs of electrons, with examples including $O_2$, $CO_2$, and $C_2H_4$.

Triple covalent bond

A bond formed by three shared pairs of electrons, with $N_2$ as an example.

Low melting and boiling points (Simple molecules)

A characteristic property of simple molecules caused by weak forces between molecules that are easy to break.

Volatile

A term describing a substance that evaporates easily.
