The Crucial Role of Kinetic Energy in Interpreting Ionization Energies
Frank Rioux and Roger L. DeKock
St. John's University / College of St. Benedict, Department of Chemistry, 37 South College Avenue, St. Joseph, MN 56374-2099

May 1998
Vol. 75 No. 5
p. 537
Abstract
The experimental ratio of the ionization energies of H and He is 1.81. We show that it is not correct to interpret this ratio using a classical Coulombic potential energy model. Rather a quantum mechanical model is required in which both kinetic and potential energy play a role.

Chemistry Teacher Connection

The "Chemistry Teacher Connection" (CTC) is especially for high school chemistry teachers. For only $40/year, it offers an online-only subscription to CLIC along with membership in the Division of Chemical Education, normally $65/year. CTC subscribers receive access to all articles and supplements from 1996 through the current issue.
