What kind of particle is produced after ionic bonding?

• molecule

• electron

• atom

• ion

How does ionic bonding take place?

• Two non-metallic elements of different kinds form strong forces of attraction.

• A non-metallic element like fluorine is attracted to a metallic element like sodium.

• Two non-metallic element of the same kind form strong forces of attraction.

• A metallic element like sodium transfers an electron to a non-metallic element like fluorine.
