Go through the first 20 elements in the chart.  Note and record which orbital contains the additional electron.  (The various orbitals are given in the upper right area of the Table.)  The filling process is fairly straight forward to this point in the Periodic Table, but becomes a little more complex as outer orbitals are filled https://www.rsc.org/periodic-table/

I am confused. It states that Nobel gasses have zero valence electrons. Then it says that group 8 elements have 8 valence electrons but group 8 are noble gases. How is this possible or am I wrong altogether? Which elements have zero valence electrons?

Imagine a universe where there are three spin states for the electron instead of two (for example, spin up, spin down, and spin cray-cray). The number of subshells per shell and number of orbitals per subshell stay the same, but an orbital now holds three electrons instead of two. The names of the elements stay the same. Draw the top three rows of what this new periodic table would look like, indicating which elements are in which groups in our new universe, and show the electron configurations of each of the elements of these three rows.

Give typed explanation of all subparts not a single word hand written otherwise leave it

Please recheck and present in clear scanned handwriting or computerized output thank you Provide the orbital diagram and electron configuration for each element:  -- K -- Rb -- Cs -- Fr Francium
