Yes. This is what's done for all elements with atomic number above
about 97 or so. The periodic table is a table organized by elemental
properties, after all.

Yes, see above. The other thing the periodic table does is organize
elements according to their electron configurations.

The correlation (as expressed in the periodic table) between elemental
properties and electron configuration then becomes more apparent.

A basic textbook in chemistry will explore this in some detail.
