Question

hydrogen is a non-metal even then it is included in the electrochemical series of Metals. Why? ​

Answer 1

here

Hydrogen is included in the reactivity series of metals because it's property of electroposivity (i.e losing electron to form positive ion) is similar to that of metals, thats why we can relate it with metals

Answer 2

Answer:

Hydrogen placed in reactive series because it has one electron in its valence shell, it shows reactivity that resembles Electropositive metals ( lose of electron and become H+).

And also reactivity that resembles Electronegative non-metals ( gain of electron and become H-).
