s belonging to the same group have similar chemical properties.Explanation:In the periodic table, there are 18 groups in which MANY elements are arranged.The elements present in each group EXHIBIT similar chemical properties.For example, the chemical properties of elements such as oxygen, sulfur, selenium, tellurium, and polonium belonging to group 16 are the same.The main reason behind this concept is that the properties of elements depend upon its valance electrons.As all the elements belonging to group 16 has the same number of valence electrons, they exhibit similar chemical properties.Learn more about such conceptWhat physical and chemical properties of elements were used by Mendeleev in creating his Periodic Table?
