I'm not sure of the exacts, but I'm fairly sure that oxygen is more reactive than hydrogen. For example, when testing with a smoldering wood splint, in the presence of oxygen gas the flame is reignited, while in the presence of hydrogen gas the splint simply glows. Again, not sure of the exacts myself, but it may have something to do with the fact that oxygen is diatomic and has a double bond with itself, leaving each oxygen atom with two unbonded pairs of valence electrons, making it more reactive. Hydrogen is also diatomic, and that means that each hydrogen atom is used in the single covalent bond, leaving it with no unbonded valence electrons, making it presumably less reactive than oxygen.
Hydrogen is more reactive , nitrogen is an nonreactive gas after noble gases

hydrogen
Because hydrogen is reactive and combines with oxygen, while helium is inert.
Helium has completely filled orbitals and is stable whereas hydrogen has one valence electron and is reactive.
Helium, argon, and neon are noble gases, so the only "reactive" element of the four is hydrogen.
helium is the most reactive, you can tell this by the amount of protrons and neutrons in it as the reactions need these to take place and the more there are the more likely it is to react like with the alkali metals the most reactice has the most protrons and neutrons
Because helium (He) is lighter than air and not flammable like Hydrogen (H) which is the lightest element.
Because hydrogen is reactive and combines with oxygen, while helium is inert.
Hydrogen and helium aren't 'out' of the periodic table, hydrogen just has characteristics that match up with group one (very reactive) and helium has characteristics that match up with group 8 (non reactive).
Helium, argon, and neon are noble gases, so the only "reactive" element of the four is hydrogen.
Helium has completely filled orbitals and is stable whereas hydrogen has one valence electron and is reactive.
Hydrogen or Helium
Hydrogen is more like Helium as it is a gas and will combust in the presence of oxygen.Even though hydrogen is placed in the same group as all the reactive metals such as sodium and potassium, this is one exception where the properties hydrogen does not match the others in the same group.

Helium has more mass than hydrogen.
Yes, Potassium is more reactive than hydrogen.
helium is non reactive.
Helium - it's less reactive.
