BONDING BASICS Covalent Bonds

Front

What is a covalent bond?

Back

A covalent bond is a type of chemical bond where two atoms share one or more pairs of electrons.

Front

What is a polar covalent bond?

Back

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

Front

What is a nonpolar covalent bond?

Back

A nonpolar covalent bond is a type of bond where electrons are shared equally between two atoms, resulting in no charge difference across the molecule.

Front

What does it mean for a molecule to be asymmetrical?

Back

An asymmetrical molecule has a shape that is not uniform, leading to an uneven distribution of charge and making it polar.

Front

What does it mean for a molecule to be symmetrical?

Back

A symmetrical molecule has a uniform shape, leading to an even distribution of charge and making it nonpolar.

Front

What is a double covalent bond?

Back

A double covalent bond is a type of bond where two pairs of electrons are shared between two atoms.

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond formed through the transfer of electrons from one atom to another, resulting in oppositely charged ions.

Front

Do covalent compounds conduct electricity?

Back

No, covalent compounds do not conduct electricity because they do not have free-moving charged particles.

Front

What is electronegativity?

Back

Electronegativity is a measure of an atom's ability to attract and hold onto electrons in a bond.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to bond in such a way that they have eight electrons in their valence shell, achieving a stable electron configuration.
