Others, for example the entrant who asked: \”What happens if you mix together all of the substances from the periodic table\”, appeared more keen to satisfy a burning curiosity.
You get dirt.
Depending upon how you mix them, in what quantities, what the original state was (for example, if you mix your Li, H and O as lithium metal and water you\’ll get a much more vigorous reaction than if you mixed them as lithium oxide plus hydrogen) various differently explosive things might or could happen, but the end result is going to be, umm, dirt.
Because that\’s what dirt is: the result of mixing all of the elements.
