Element Groups

Element groups are categories of chemical elements that share similar properties and behaviors because they have the same number of electrons in their outermost shell. These groups are organized in columns on the periodic table. For example, the alkali metals (like sodium and potassium) are highly reactive, while the noble gases (like helium and neon) are inert. Grouping elements helps scientists predict their characteristics, how they bond with other elements, and their uses in various applications. It’s a way of understanding the similarities and differences among elements based on their electronic structure.
