Reactive towards what?
If you put sodium in water, you'll see some serious reactivity (not recommended). If you put the same chunk of sodium in air, you won't see much reactivity (even though there is a reaction going on).
As a practising chemist, I would rate potassium and/or sodium as the most "reactive" metals. They are the most likely to burst into flames upon exposure to water.

Most Reactive Metal
2016-11-09 21:44:26 · answer #2 · answered by moyle 4 · 0⤊ 0⤋
according to my schools reactivity seies, the most reactive metal is sodium but ... in a video i saw group 1 metals are the most reactive they form basic oxides right? then if you go down group 1 , the reactivity if the metals increase ... density increases and so basically .. shouldn't Francium the last at the group one be most reactive? i have seen caesium blow up a bowl of water but my teacher did not show anything on fracium. i guess that is the answer of your question
sorry if my stupid answer confused you ..

Most definitely Francium (although it is radioactive so that's why you don't see it often). Reactivity of the alkaline metals increases as you go down the group. Lithium would be the least reactive of these, followed by sodium, etc.

Oh my God!!!
I can believe almost every one here is so ignorant.
The most reactive metal is definitely not lithium you dunderheads and copycats!
The Most reactive metal is francium.
In group one in the periodic table, the elements at the top are less reactive than the elements at the bottom of the group.
And so do the reactivity of group 2 metals decrease as you go down the group. And the metals in group 2 are less reactive than the metals in group one and thats because they have to give out two electron shells before their atoms become stable.

Francium (Fr) is the most reactive with water and it's radioactive. Personally i like the Cesium and water explosions. they're fun to watch. Zinc reacts violently with acid. It all depends on what you're reacting the metal with which is more reactive

Most reactive NON-METAL is fluorine, F
I'm not sure about metal. Which element has the smallest electronegativity? That would be the answer. Possibly francium, but there is so little francium in the world, what element is above francium on the Periodic Table.

Francium is the most reactive metal.

theoritical explanations certainly fix francium, but it'll be judicial to mention cesium as the most reactive one, because francium is a radioactive element, so it may show some uncertainity. but cesium is much more responsive practically and it is used as the most reactive metal practically.

The most reactive metal is Francium. However there is little of it. The next would be Rubidium. The most active metal is the one most likely to give away it' s outer electron. This is where Francium is the most active because the one outer electron is the farthest from the nucleus holding it.
The most active nonmetal is Fluorine, because it is the nonmetal most likely to grab an electron to fill its outer ring.and those electrons are closest to the nucleus.
