Question

why carbon and hydrogen are placed in the reactivity series of metal if they are non-metal?​

Answer 1

Explanation:

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-). ... This is the reason hydrogen is placed in the reactivity series of metals.
