In our universe, the arrangement of the elements in the periodic table is a direct consequence of their four quantum numbers, $n, l, m i$, and $m_{s}$. For example, all Group 1 elements have a similar electron configuration of 1 electron in the outermost $s$ orbital. This configuration determines many of the group's chemical properties. Imagine a new universe in which this chemical reality has changed, and the universe now follows a different set of quantum number rules - the old rules no longer apply. In the new universe, the following change occurred: \[ m_{l}=-(n+1) \text { to }(n+1) . \] All of the other quantum numbers remain the same. This change in one quantum number changes not only the laws of physics, but the periodic table as well - the chemical properties of the elements change. Your new universe is made of elements that are arranged differently and follow a different set of fundamental standards from the elements in the universe. You are responsible for developing a new periodic table of the first 40 elements. You will need to complete this new table based on the new definition of the magnetic quantum number. This exercise will help you understand how chemists developed the original periodic table that we use today. In this task, you will test your understanding of the use of quantum numbers to describe the organization of elements in the periodic table.

Procedure 1. Using enough space for 40 elements, draw the outline of your new periodic table in which elements have a magnetic quantum number of $m_{l}=-(n+1)$ to $(n+1)$. 2. Identify the groups and periods in your new periodic table. 3. Add the elements in your new table.

This is regarding the magnetic quantum number.

the questions regard magnetic quantum numbers. If the magnetic quantum number were to change from the regular formula to the formula of ml = -(n+1) to (n+1) what would the new periodic table look like. What are the new groups that would follow.
