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. Suppose, in a different universe, the quantum number ms only has the allowed value of ms = +. All other allowed values are unchanged.

1. . Design the periodic table for the first 40 elements.

2. what variables did you use in this activity? what did you change? what was the result of each change?

3. explain how the numbers of electrons allowed into the s, p, and f orbitals has changed from the real periodic table

4. in the new periodic table, why is there a different number of elements in a given period compared to the real periodic table

5. in the new periodic table, why is there a different number of groups compared to the real periodic table

6. how many of the first 40 elements are probably non-metals? why?

7. what is the electron configuration of element 20 in the new periodic table
