the more vigorous its reactions are the more easily it loses electrons in reactions to form positive ions (cations) The table summarises some reactions of metals in the reactivity series. Hydrogen and ...

Alkali metals can react explosively with water and it is textbook knowledge that this vigorous behaviour results from heat release, steam formation and ignition of the hydrogen gas that is produced.

When a chunk of alkali metal gets tossed into water, it explodes. But when a team of scientists gently placed a liquid drop of a sodium-potassium alloy on top of a water surface, they observed a ...

The reactivity series is a list that shows the order of reactivity of some common metals. Calcium (Ca) Reacts vigorously with strong heating. Brick red flame observed and white solid formed. 2Ca + O 2 ...
