Peer reviewedDigilov, M. – Quantum, 1991
Discusses 5 innovative experiments conducted by Rutherford in early 1900s utilizing the 30 milligrams of radium salt he personally carried from Europe to Canada in 1903. Traces his work with alpha particles from his original results which determined their nature, charge, and mass, to his technique of backscattering which helped to advance…

Periodicity and Some Graphical Insights on the Tendency toward Empty, Half-full, and Full Subshells.
Peer reviewedRich, Ronald L.; Suter, Robert W. – Journal of Chemical Education, 1988
Investigates ground state electron configurations for some common elements using graphical methods. Bases observed tendencies on following ideas: "occupancy of differing shells, occupancy of differing subshells within a given shell, double occupancy vs. single occupancy of an orbital, and quantum-mechanical exchange."
