Look up chemical element names, symbols, atomic masses and other properties, visualize trends, or even test your … WebOne thing I saw was that the 3d subshell is a bit more compact, making the 4s preferred in certain cases. As you might suspect it depends on the atomic number (aka the # of protons). As we go down the periodic table the nuclear strong force increases, and somehow this effects the choice to choose 3d over 4s or vice versa.
