Ga has a nfpa code of 1 on reactivity and Se has a reactivity of 2.
Zn is more reactive than Ga, Cd is more reactive than In; but Tl is more reactive than Hg.
No. More reactive halogens will replace less reactive ones in a compound. This is because a more reactive halogen is more stable in a compound relative to a less reactive one, while a less reactive halogen is relatively more stable in its elemental form.
Hydrogen is more reactive than Copper, but less reactive than Zinc which is less reactive than Magnesium which is less reactive than Potassium. Potassium is the most reactive of all, relatively speaking.
less reactive
chlorine (Cl)
No, it is less reactive.
Gold is a less reactive metal but not non-reactive; all metals are reactive.
Bromine is way more reactive
it displaces the less reative metal and replaces it.

Hydrogen (H) is more reactive. Francium (Fr) is less reactive.
Aluminium is much less reactive than Lithium.
