Chapter 28, Problem 13Q

To determine

The structure of Periodic Table in the absence of electronic spin.

Answer to Problem 13Q

Solution:

One orbital can hold only one electron. The table looks a bit like this.

Explanation of Solution

The Pauli Exclusion Principle would still apply, which forbids two electrons from being in the same state. Usually, two electrons have opposite spin and can be accommodated in the same orbital; but here an orbital can contain just one electron.

The periods would need to double, while the groups would half (as each orbital is used once).
