Due to the spin of the unpaired electron in a Group 1 atom, the ground state is doubly degenerate, but the atoms in Groups 2, 12, and 18 have non-degenerate ground states. The lowest energy configurations of the atoms in Groups 13-17, on the other hand, give rise to several non-...

Today’s objectives LO 1.9 - The student is able to predict and/or justify trends in atomic properties based on location on the periodic table and/or the shell model. Students can make predictions about trends in electronegativity and first ionization energy....
4Periodic trends in atomic and ionic radii The original purpose of the periodic table was to organize the the chemical elements in a manner that would make sense of the ways in which the oobserved physical and chemical properties of the elements vary with the atomic number. In this section, ...
