What sort of periodic table would hang on the wall in Bizarro's classroom? Probably the periodic table of antimatter—the anti–periodic table.

Imagine that Superman's opposite-in-all-ways enemy, Bizarro, taught high-school chemistry. (Bizarro does enjoy inflicting punishment, after all ...) What sort of periodic table would hang on the wall ...

We believe that there is an anti-periodic table, right, that you could have an anti-universe full of anti-elements. But it’s very difficult for us to go and do atomic physics on those.

Physicists have created the heaviest clumps of antimatter particles ever seen. Known as antihyperhydrogen-4, this strange stuff could help us solve some of the most puzzling physics mysteries.

At the moment physicists are having enough difficulty just taming antihydrogen, the simplest possible anti-atom. Can we ever expect them to make a whole anti-periodic table?

The periodic table is a letdown in another sense, too: Given all its columns and rows, it looks like it should contain dozens of different types of elements, but there are really only a few. Most ...

Columns in the periodic table are called groups or families. Elements within the same group share similar properties because they have the same number of valence electrons (electrons in the ...
