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

Back

A bond formed when two atoms share one or more pairs of electrons.

Front

What is the charge of a positive ion?

Back

It has a positive charge due to the loss of one or more electrons.

Front

What is the charge of a negative ion?

Back

It has a negative charge due to the gain of one or more electrons.

Front

What is the octet rule?

Back

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