because they only have 1 electron in their outer shell and as a result are very reactive.

They are highly reactive and will oxidize in the presence of water or virtually anything. So they do not last long in nature...

They have only 1 valence(outermost) electron and so they are very reactive, losing their valence electron to form compounds.

They are in general too reactive to be alone in nature.

they are highly reactive so much so that they form compounds almost immediately., they have one outer electron so it loses it rapidly...
