Potassium ions (K^+#) have a positive charge. What happens to a potassium atom's electrons when it becomes an ion?
Well, usually they have caused a reduction in another reagent.
A tiny piece of potassium is dropped into water, causing some of the water to be reduced to dihydrogen. This can be represented by two redox rxns:
In general,
Lithium or sodium work better in a teaching lab to illustrate this reaction; potassium produces a lot of spritz and sparx.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
