By the periodic table’s logic, all d-block elements should have filled s orbitals. But copper defies that logic. It should have the electron configuration [Ar] 3d 9 4s 2 .
Physicists develop a 'nuclear periodic table'. While the traditional table is based on the behavior of electrons in an atom, this new table is based on the protons in the nucleus. Protons have ...
