1+ charge.

Front

What do anions do?

Back

Gain electrons.

Front

What is an ion?

Back

An atom or molecule with a net electric charge due to the loss or gain of one or more electrons.

Front

What is the charge of a cation?

Back

Positive charge.

Front

How do you determine the charge of a transition metal ion?

Back

By considering the number of electrons lost from the outer shell.

Front

What is the significance of the octet rule in ion formation?

Back

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