Chemical Bonding

Front

What is a covalent bond?

Back

A covalent bond is the force of attraction that holds together two nonmetal atoms that share a pair of electrons.

Front

What is an ionic bond?

Back

An ionic bond is the force of attraction that holds together oppositely charged ions.

Front

How many electrons does oxygen need to achieve a full valence shell?

Back

Oxygen needs 2 more electrons to achieve a full valence shell and be chemically stable.

Front

What do bonds form when atoms share or transfer?

Back

Bonds form when atoms share or transfer valence electrons.

Front

How many total valence electrons does O2 have?

Back

O2 has a total of 12 valence electrons.

Front

What are valence electrons?

Back

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

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 type of bond involves the transfer of electrons?

Back

Ionic bonds involve the transfer of electrons from one atom to another.

Front

What type of bond involves the sharing of electrons?

Back

Covalent bonds involve the sharing of electrons between atoms.

Front

What is a metallic bond?

Back

A metallic bond is the force of attraction between metal atoms and the surrounding sea of electrons.
