In this video excerpt from NOVA's "Hunting the Elements," New York Times technology columnist David Pogue examines how atomic structure determines reactivity. Meet Theo Gray, chemist and author ...

A milestone in chemistry was achieved through the use of fluorine: the discovery of the reactivity of noble gases — when xenon fluoride was prepared by Neil Bartlett in 1962 — which challenged ...

The noble gases are the chemical elements in group 18 of the periodic table. They are the most stable due to having the maximum number of valence electrons their outer shell can hold. Therefore ...

PARIS, June 14 (Reuters) - French power group EDF EDF.PA said on Monday it had been informed of the increase in the concentration of certain noble gases in the primary circuit of reactor no 1 of ...
