Question

Why is Hydrogen included in the reactivity series of metals?

Answer 1

hydrogens behaves like both alkali metals(e.g. Na and K) as it shows the behaviour like these metals by loosing an electron forming H+ (hydronium ion) easily which reacts with non metals like Cl forming HCl(Hydrochloric acid or hydrogen chloride) and with other halogens forming acids. On the other hand H also has the ability to gain one electron to form H-(Hydride ion) like that of non metals like Cl and reacts with other metals like Na or K forming NaH (sodium hydride) So Hydrogen is put in the activity series of metals....
