WebThe valencies of the elements belonging to the s-block and the p-block of the periodic table are generally calculated as the number of valence electrons or eight minus the number of valence electrons. For the d-block and f-block elements, valency is determined not only on the basis of valence electrons but also on d and f orbital electrons.

Extended periodic table - Wikipedia
WebThe periodic table is a tabular display of the chemical elements organized on the basis of their atomic numbers, electron configurations, and chemical properties. The electron configuration is the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals.
