Periodic classification of elements is the method by which elements are grouped on the basis of their characteristics i.e. we keep the elements that are alike in one group and the rest of the elements in the other group. Some empty spaces have been left in the periodic table so that the elements that will be discovered in the future can be placed without disturbing the trending periodicity of the elements. Classification of elements in groups provide us with a fixed pattern in which the elements change their properties periodically. The periodic table made the study of the physical and chemical properties of elements simple and organized. We can now just go to the group and see the properties of the elements of the periodic table or predict the properties of an element if we know the characteristics of other elements present in the same group. Although there are so many elements that are already discovered, there are chances that new elements can be discovered. Scientists can take the help of a periodic table and know the trending characteristics based on the properties of elements and hence can identify the new elements with the existing ones.
