What is a nonpolar covalent bond?

Back

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

Front

What is a polar covalent bond?

Back

A polar covalent bond is a type of bond where electrons are shared unequally, resulting in a slight charge difference.

Front

What is the significance of valence electrons in covalent bonding?

Back

Valence electrons are the electrons in the outermost shell of an atom and are involved in forming covalent bonds.

What is an example of a molecule with a double bond?

Back

An example of a molecule with a double bond is oxygen (O2).

Front

What is the difference between a single bond and a double bond?

Back

A single bond involves one pair of shared electrons, while a double bond involves two pairs of shared electrons.
