“The periodic table is supposed to tell you what the chemical trends are,” LBNL’s Pore says. For heavier elements, in which relativistic effects start to rule, that’s not necessarily true.

A high-tech need Helium is the second element on the periodic table, which—as you may recall from high school chemistry class—means it has just two protons (and thus two electrons).

Helium is the simplest element in the periodic table with more than one particle in its nucleus, yet state of the art theory and experiments on it don't add up.

For example, Hydrogen, with an atomic number of 1, comes first, followed by helium (atomic number 2), and so on. Rows in the periodic table are called periods.
