Front

What is the octet rule in chemistry?

Back

Atoms tend to form compounds in ways that give them eight valence electrons.

Front

What type of bond involves the sharing of electron pairs between atoms?

Back

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.

Front
