cation.

Chlorine is a Halogen in the 17th column or

p

5

group.

Chlorine has 7 valence electrons. It needs one electron to make it stable at 8 electrons in its valence shells. This makes chlorine a

1

anion.

Ionic bonds form when the charges between the metal cation and non-metal anion are equal and opposite. This means that two
