What is a covalent bond?

Back

A covalent bond is a type of chemical bond where two nonmetal atoms share pairs of electrons.

Front

What types of atoms typically form covalent bonds?

Back

Covalent bonds are typically formed between two nonmetals.

Front

How many valence electrons does nitrogen have?

Back

Nitrogen has 5 valence electrons.

Front

What is 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.

Front

What is the state of most covalent compounds at room temperature?

Back

Most covalent compounds exist as gases or liquids at room temperature, and very few are solids.

Front

How do covalent bonds differ from ionic bonds?

Back

Covalent bonds involve the sharing of electrons, while ionic bonds involve the transfer of electrons from one atom to another.

Front

What is a molecule?

Back

A molecule is a group of two or more atoms bonded together by covalent bonds.

Front

What is a polar covalent bond?

Back

A polar covalent bond is a type of covalent bond where electrons are shared unequally between 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 atoms.

Front

What determines the number of bonds an element can form?

Back

The number of bonds an element can form is determined by the number of electrons needed to reach an octet.
