"Oxford ecologist Philip Stewart has designed a new periodic table of the elements, and it's a hit. American schools are placing orders daily for Stewart's table, and the Royal Society of Chemists recently sent a copy to every British secondary school. Stewart's is the only remake to achieve widespread adoption since Dmitri Mendeleev invented the original periodic table in a fit of brilliance in 1869. "

Very cool!

Why is Hydrogen given the same color code as the Group IV A elements (C, Si, Ge, Sn, Pb)? Its chemical behavior is nothing like these tetravalent elements. Hydrogen probably belongs in a category of its own but if it must be shoehorned into one of the groups, Group I A (one electron in the outermost shell) would be far more suitable, though Hydrogen sometimes behaves like a Group VII A element (one electron missing in the outermost shell).
