Noble gas aided in the development of a general understanding of atomic structure. In 1895, French chemist Henri Moissan attempted to form a reaction between fluorine, the most electronegative element, and argon, one of the noble gases, but failed. Scientists were unable to prepare compounds of argon until the end of the 20th century, but these attempts helped to develop new theories of atomic structure. Learning from these experiments, Danish physicist Niels Bohr proposed in 1913 that the electrons in atoms are arranged in shells surrounding the nucleus, and that for all noble gases except helium the outermost shell always contains eight
The More Abundant Life I am come that they might have life, and that they might have it more abundantly." Roosevelt, an Episcopalian, would also have been familiar with a similar phrase used in the collect for the Fifth Sunday after the Epiphany in the "Book of Common Prayer".
