What is a covalent bond?

Back

A covalent bond is a type of chemical bond where two non-metal atoms share pairs of electrons.

Front

How do you identify a covalent compound?

Back

Covalent compounds usually consist of non-metals and have low melting and boiling points.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons from one atom to another, while covalent bonds involve the sharing of electrons.

Front

What is the significance of the octet rule in covalent bonding?

Back

The octet rule states that atoms tend to form bonds until they are surrounded by eight valence electrons, achieving a stable electron configuration.

Front

What is a polar covalent bond?

Back

A polar covalent bond is a type of covalent bond where electrons are shared unequally between two atoms, resulting in a molecule with a slight charge.

Front

What is a nonpolar covalent bond?

Back

A nonpolar covalent bond is a type of covalent bond where electrons are shared equally between two atoms.
