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.
