Day 3 Pre-Class Podia Problem: Quantum Numbers and the Periodic Table

This Podia problem is based on today’s pre-class material; working through that material will help you solve the problem.

In a hypothetical parallel universe, the quantum numbers are defined differently: n, ℓ, and ms obey the same rules as in our universe, but m cannot have negative values. Thus, a p subshell contains only two p orbitals, a d subshell contains three d orbitals, and so forth. The energies of the subshells are the same as in our universe. In your notebook, answer each question below and explain each answer clearly, concisely, and with scientifically appropriate language.

  1. Draw a periodic table for the hypothetical universe.
  2. Determine the atomic number of the fourth noble gas element.
  3. Write the electron configuration of the third halogen (the element in the periodic table you drew that has atomic number one less than the third noble gas element)

Two days before the next whole-class session, this Podia question will become live on Podia, where you can submit your answer.
