Assignment #1 - Atomic Theory and Bonding
Part One: Quantum Number Thought Experiment
The arrangement of elements in the periodic table is a direct consequence of the allowed
values for the four quantum numbers. If the laws of physics allowed these numbers to
have different values, the appearance of the periodic table would change. In this
activity, you will examine the effect on the periodic arrangement of the elements when
one of the quantum numbers has a different set of allowed values.
Suppose, in a different universe, that the quantum number ml has only one allowed
value. All other allowed values for the remaining quantum numbers are unchanged.
Therefore the set of allowed quantum numbers is:
n = 1,2,3 …..
l = 0,1,2…..n-1
ml =-n to n
ms = +1/2 or -½
A. Assuming that the exclusion principle and Hund’s rule are followed, draw a
periodic table showing the first 40 elements, and indicate the “blocks” on the
periodic table.
