Outer Orbital Block Periodic Table
This Periodic Table shows the general relationship of each element’s outermost electron orbitals. You can see the trends easily with this table. As the atomic number increases, s orbitals are filled first, followed by p orbitals. The transition elements are the beginning of filling the d orbitals and the lanthanides […]
