Periodic table, in chemistry, the organized array of all the chemical elements in order of increasing atomic number. When the elements are thus arranged, there is a recurring pattern called the ‘periodic law’ in their properties, in which elements in t
Groups, also known as families, are the 18 vertical columns of the periodic table. Elements within the same group have similar chemical properties because they have the same number of electrons in their outermost shell, which determines how they react with other elements. For instance, all elemen...
