8.2 The Nature of Covalent Bonding Review

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 to achieve a full outer shell of electrons.

Front

What is the Lewis structure?

Back

The Lewis structure is a diagram that represents the bonding between atoms of a molecule and the lone pairs of electrons that may exist.

Front

What is resonance in chemistry?

Back

Resonance refers to the way in which some molecules can be represented by two or more valid Lewis structures, which contribute to the overall hybrid structure.

Front

What is a coordinate covalent bond?

Back

A coordinate covalent bond is a type of covalent bond where one atom provides both electrons for the 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.

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 between atoms.

Front

What are lone pairs?

Back

Lone pairs are pairs of valence electrons that are not involved in bonding and belong exclusively to one atom.

Front

What is a polar covalent bond?

Back

A polar covalent bond is a type of bond where the electrons are not shared equally between the two atoms, resulting in a dipole moment.

Front

What is a nonpolar covalent bond?

Back

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

Front

What is the significance of electronegativity in covalent bonding?

Back

Electronegativity is a measure of an atom's ability to attract and hold onto electrons; it helps determine the type of bond (polar or nonpolar) formed between atoms.
