Front

How do covalent bonds form?

Back

Covalent bonds form by sharing valence electrons between atoms.

Front

What is an ionic bond?

Back

An ionic bond is formed when one atom donates an electron to another atom.

Front

What is a covalent bond?

Back

A covalent bond is formed when two atoms share one or more pairs of electrons.

Front

What are valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in chemical bonding.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of 8 electrons.

Front

What is a polar covalent bond?

Back

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