Term & Spin State Periodic Table

A Tern & Spin State periodic table by Gnanamani Simiyon who writes:

"We tried to arrange the elements based on the ground state term and spin state. I attached picture of the periodic table drawn. For example, I notice that alkali metals and coinage metals grouped up indicating some relationship between the groups. Similarly with respect to alkaline Earth metals and Zinc group. We are unable to further understand other groupings based on the ground state term and spin state."
