Front

What is an ionic bond?

Back

A bond formed by the transfer of electrons from one atom to another, resulting in the formation of positive and negative ions.

Front

Front

What is the charge of an anion?

Back

Negative.

Front

What is the octet rule?

Back

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

Front

What is the difference between polar and non-polar covalent bonds?

Back

Polar covalent bonds have unequal sharing of electrons, while non-polar covalent bonds have equal sharing.
