Front

What is the octet rule?

Back

Atoms tend to gain, lose, or share electrons to achieve a full outer shell of 8 electrons.

Front

What is a Lewis structure?

Back

Front

What are core electrons?

Back

Electrons that are not involved in bonding and are located in the inner shells of an atom.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons, while covalent bonds involve the sharing of electrons.
