Fluorine....

#### Explanation:

Teflon, the coating for non-stick cooking items, is polytetrafluoroethylene, i.e. ${\left(- C {F}_{2} - C {F}_{2} -\right)}_{n}$. Fluoride is used by dentists to build up and strengthen enamel, i.e. $C a {F}_{2}$. It is a fact that many fluorine chemists are missing eyes and fingers due to the EXTREME reactivity and oxidizing power of elemental fluorine.

A solution of fluoride salt in water would be SLIGHTLY alkaline due to the equilibrium...

$N a F \left(a q\right) + {H}_{2} O \left(l\right) r i g h t \le f t h a r p \infty n s N a O H \left(a q\right) + H F \left(a q\right)$

In the following reaction, what has been oxidized, and what has been reduced?

$\frac{1}{2} {O}_{2} \left(g\right) + {F}_{2} \left(g\right) \rightarrow O {F}_{2} \left(g\right)$
