- The simplest radical is the hydroxide ion which is made up
- of hydrogen and oxygen.

- Try using the bonding machine to bond a single oxygen to
- a single hydrogen atom covalently.

- The oxygen atom is still one electron short of a full complement
- in its outer shell. It is therefore unstable in this state and requires
- an extra electron.
