What element that you want to control?

This made me think of this thread...

Oh goody, goody! Will jam people with mercury!

Antihydrogen.

Antihydrogen.

Why?
Also what are the uses of Antihydrogen? (I don't see it being useful in synthesis because we can't use antiwater)

[Bloodshadow]

Annihilation, of course. If I can produce at will the element I've chosen, I'll have the most powerful energy source and explosive in existence. Hmm, maybe I should go with antideuterium instead, so that I have protons, neutrons, and electrons all covered. But then again, I can always make neutrons by forcing the electron and proton inside a hydrogen atom to undergo reverse beta decay, if my control extends that far.

If we cannot create the element we control, and can only control already existing atoms of the element, then the obvious choice would be carbon or hydrogen or some other common element. And that's boring.

[OldTrees]

So no uses beyond annihilation? Aw

I will stick with H since I can construct or deconstruct what I want.

Wondering if we're allowed to control some forms of exotic matter. Like, replacing the up and down quarks in our atoms with some other types of quarks, and replacing the electrons with some other types of leptons. That'd give them radically different, and possibly very interesting, properties. Normally exotic matter like those are highly unstable, but we shouldn't be able to stabilize them with our element-controlling magic or whatever.

@Bloodshadow: Why not antiiron? Iron has the strongest binding energy. This idnicates that if iron and antiiron collide there will be much more energy released per unit mass rather than the puny antiproton. Furthermore, Iron is very abundant and it is the cause for stars to cease.

[Bloodshadow]

Assuming that I can produce an unlimited amount of my chosen element, it doesn't really make any difference what element I choose if I just want annihilation. Or does it...

Whatever. This whole thing is rather ambiguously defined. Analyzing it too deeply will probably make it fall apart and ruin the whole point.

Most definitely Lithium. Why? Because I'd be able to create awesome bombs just by using water. eue I really like exploding things.
I'd say this would be the best Alkali Metal choice for the best bomb since it has the smallest atomic radius among the others, which would require a larger amount of energy to oxidize it to its Li+ form. Sure, it'd take a little longer than if I chose to use Francium for example, since its atomic radius is the largest of the entire periodic table and its electron are much more "movable" if you know what I'm saying. But the boom would be totally worth it EuE

I'd love to have some booms here and there eue

maybe I'm a little psycho. teeny bit.

Definitely hydrogen; it's the most common element in the universe and is a big part of virtually every organic compound.

I concur. Absolutely the best choice. Plus think about water... or hydrogen bombs.
