A Different Approach to a 3-D Periodic System Including Stable Isotopes
Alexandru T. Balaban
Organic Chemistry Department, Polytechnic University, Bucharest, Romania
Cover
March 1999
Vol. 76 No. 3
p. 359
Abstract
On a Periodic System with the two dimensions represented by Periods and Columns, one may stack each stable nuclide of an element along the third dimension. This "Downtown Area" representation is helpful for interconnecting concepts of: element, isotope or nuclide (stable vs. radioactive), atomic weight, atomic number, mass number.
