Potassium is more reactive than sodium
It will produce a salt and hydrogen gas.For example :2HCl + Mg --> H2 + MgCl2OR : 2HCl + Zn --> H2 + ZnCl2Please note that the metal should be more active than hydrogen, because Copper or Silver for example can't react with hydrogen because they are less active than it.
It does not cause a reaction. Ag (Silver) is less active than Cu (Copper). The element has to be MORE active in order for a reaction to occur.

Potassium is more reactive than sodium
it is the lithium metal. it is less reactivated.
Human body has more resistance than metal because it has less conductor for carrying electrons.
Zn is more reactive than Ga, Cd is more reactive than In; but Tl is more reactive than Hg.
metal oxides are basic in nature.. so their pH is more than 7
The Pauling electronegativity of hydrogen is higher than the electronegativities of aluminium or copper.And copper is more reactive than aluminium.The red poweder obtained is copper as a metal.
Hydrogen (H) is more reactive. Francium (Fr) is less reactive.
not any more/less than other music
the solubility of alkali metal bases is more than the solubility of alkaline metal bases. thus the reaction: base=metal ion + OH- occus faster. since the more the OH ions the stronger the base, alkali metal bases are stronger than alkaline metal bases
