Why is Hydrogen so reactive? What makes it combustible?




Hydrogen is not particularly reactive. 


For example, just mixing hydrogen and oxygen gas will not cause a reaction at room temperature, but many metal elements oxidize at least on the surface in air. 


The most reactive elements in my opinion are fluorine in the non-metals, and the alkali metals like sodium and potassium.


It is combustible because oxygen wants electrons and takes them from hydrogen to form water.
