Elements in the same group share similar chemical properties from "summary" of The Periodic Table: A Very Short Introduction by Eric R. Scerri
Elements situated in the same group of the periodic table exhibit analogous chemical behavior. This generalization holds true for the majority of the groups in the table. For instance, the alkali metals, found in Group 1, are known for their high reactivity with water. They readily form ionic compounds and display similar trends in reactivity down the group. Moving across the table, the halogens in Group 17 also share common characteristics, such as high electronegativity and the ability to form salts with metals. The underlying reason for this similarity in chemical properties lies in the electronic configuration of these elements. Elements within the same group possess the same number of electrons in their outermost energy level, also known as the valence shell. This shared electron configuration results in comparable chemical reactivity as elements strive to achieve a stable electron configuration by either gaining, losing, or sharing electrons. Moreover, the periodic table is structured in a way that elements in the same group have the same number of valence electrons. This commonality in electron configuration directly influences the elements' ability to form chemical bonds and participate in reactions. For example, elements in Group 14 have four valence electrons, leading to a tendency to form covalent bonds and exhibit a variety of oxidation states. By organizing elements based on their atomic number and electronic structure, the periodic table highlights the recurring patterns in chemical behavior. This systematic arrangement allows scientists to predict the properties of unknown elements based on their position in the table. Understanding the concept that elements in the same group share similar chemical properties is fundamental to grasping the periodic table's utility in elucidating the behavior of elements and their compounds.
