Group 1 elements.
Francium would be one of the most reactive as it has many electrons and it doesn't know when one is being taken away (hence reacting with something else) It also has only 1 electron on the outer shell, making it VERY unstable.

Anything in Group 1A (ex: H, Li) or 7A (ex: F) because those are the elements that are most desperate to give away or steal a pair of electrons. Why are they so desperate, you ask? Well, because atoms in general are more chemically active when there is an orbital, or shell, left unfilled by electrons. Explaining why an atom that has only one extra pair of electrons is more reactive than an atom with two extra pairs requires an understanding of how shells are filled and the Aufbau principle. Also, if you go down groups 7A for example, Fluorine is more reactive than Chlorine which is more reactive than Iodine, etc. This is because Chlorine is a larger atom and forms a weaker bond than Fluorine

The most chemically reactive element in the periodic table is potassium( K ) according to me.

If most chemically reactive means lowest 1st ionization potential, then Cesium carries away the honors for stable elements with a 1st ionization potential of 3.9 ev.
(and here I always thought it was Hydrogen or Fluorine!)
(I rejected Francium because it has no stable isotopes)

this question doesn't have a specific answer because there are several types of reactions. the two most famous ones:
in oxidation reactions (loosing electron) cesium (Cs) is the most reactive.
in reduction reactions (receiving electron) fluorine is the most reactive.
but this is not a certainty, since the condition of the reaction might change it. for example hydrogen receives electron easier than Potassium in normal conditions, but potassium will reduce faster than hydrogen if reaction takes place on the surface of mercury.

Fluor.
It is the most electronegative element, which makes it the most reactive.

I'll go for oxygen, and I'm an idiot on chemical reactions. Carbon bonds with everything, too, and silicon is not not bad, but oxygen is the key to a good fireworks display...
I'll check back for answers by the experts. But I won't hold my breath...

I'd say francium for metals and fluorine for non metals.. anyone agree? i don't know about man-made ones...

anything in the first row under hydrogen or ones man made and radioactive.
