WebThe columns of the periodic table, which contain elements that show a family resemblance, are called groups. All members of a particular group have analogous outermost (valence) electron configurations, suggesting that all members of a group should show a family relationship in the types and numbers of the chemical bonds that they are able to form. … WebThe first period of the modern periodic table is the shortest period as it contains only two elements. The period number two and three consist of eight elements each and are known as short groups. Period four and five …
WebSep 22, 2024 · The periodic table has three short periods, and the rest are long periods. The groups start with alkali metals and end with noble gases. The representative elements are called s and p block elements. WebAlthough the table was originally organized on the basis of physical and chemical similarities between the elements within groups, these similarities are ultimately attributable to orbital energy levels and the Pauli principle, which cause the individual subshells to be filled in a particular order.
