Ionic and Covalent Bonding

Front

What are valence electrons?

Back

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

Front

What type of bond involves the transfer of valence electrons?

Back

Ionic bonds involve the transfer of valence electrons.

Front

What type of bond involves the sharing of valence electrons?

Back

Covalent bonds involve the sharing of valence electrons.

Front

What is an ion?

Back

An ion is an atom or molecule that has a net electrical charge due to the loss or gain of one or more electrons.

Front

What is the difference between cations and anions?

Back

Cations are positively charged ions (lost electrons), while anions are negatively charged ions (gained electrons).

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 eight electrons.
