Left-step Periodic Table
What do folks think about the recently rediscovered left-step periodic table as supported in my book on the periodic table (E.R. Scerri, The Periodic Table: Its Story and Its Significance, Oxford University Press, 2007) and in a recent article by Bent and Weinhold in the Journal of Chemical Education (July issue)?
This is a form of the table that places He among the alkaline earths.
Other features: No break in continuity of elements, meaning no gaps between Be and B or between Mg and Al.
Better display of the n + l electron filling rule than the conventional of medium-long form table.
