Potassium is the most reactive. All of the elements in the first column of the Periodic Table are extremely reactive to water. These elements all have on more electron than the stable noble gas configuration (an octet in the valence shell), and so by getting rid of that extra valence electron, the element becomes much more stable. In contact with water, these elements will give this extra electron off to the water, forming hydroxide (OH-) and becoming a positive ion. For example, when you add potassium metal (K) to water, you will form the positive ion K+, which has the same electron configuration as argon, with a completely filled valence shell. The other metals listed will not react very quickly at all with water (unless it is very acidic water).

What is the reactivity of sodium?
Very high. It's an alkali metal, in the most reactive metal family. Don't get me wrong, it's the weakest of the alkali metals, but more reactive than any other metals. For a VERY violent reaction, try potassium. For a VERY dangerous reaction, use pure francium.
What metals react with air?
Potassium, sodium, lithium, calcium, magnesium, aluminium and iron all react with air. The reaction creates an oxide. Iron reacts the slowest whereas aluminium reacts the fastest.
Is Hydrogen produced when Magnesium reacts with copper sulfate solution?
The activity series of metals goes something like this: Lithium Potassium Barium Calcium Sodium Magnesium Aluminum Zinc Iron Nickel Tin Lead Hydrogen Copper Mercury .............and so on..... ps, I might have left some elements out....can't remember them all... Since magnesium is higher in the reactivity series of metals, it can replace copper in a reaction. Copper is lower in the activity series of metals therefore can not replace magnesium.
