Why not hydrogen placed at the top of the reactivity series?
Answers
Explanation:
Despite being a non-metal, hydrogen is often included in the reactivity series since it helps compare the reactivities of the metals. The metals placed above hydrogen in the series can displace it from acids such as HCl and H2SO4 (since they are more reactive)

Explanation:
In the periodic table, hydrogen is placed is the first row just before inert gas Helium. Because it has one electron in its valence shell, it shows reactivity that resembles electropositive metals (lose an electron and become H+) and reactivity that resembles electronegative non-metals (gain an electron and become H-)
