Answer to Question #278129 in General Chemistry for Jorille

Question

Suppose that spin quantum number could only have a -1/2,0, and +1/2 and assuming that the rules governing the values of the other quantum numbers and the order of filling sublevels were unchanged.What would be the electron configuration of the element with an atomic number of 17. give explanation

Answer 1

After this hypothetical condition, every orbital can have 3 electron.

As in second orbit, 4 orbital are there so total no. of electron is 4×3=12. 

Second period would have 12 elements.

Third period would have 12 elements.

Periodic table would contain 18×3/2=27 groups
