Front

Define a covalent bond.

Back

A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms.

Front

What is the difference between polar and nonpolar covalent bonds?

Back

Polar covalent bonds involve unequal sharing of electrons, while nonpolar covalent bonds involve equal sharing.

Front

What type of bond is formed between two nonmetals?

Back

Covalent bond.

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond that involves the electrostatic attraction between oppositely charged ions.

Front

What is the significance of lone pairs in Lewis structures?

Back

Lone pairs represent non-bonding electrons that can affect the shape and reactivity of molecules.
