Properties of Periodic Table of Element Groups

11/11/2019· One reason the periodic table of the elements is so useful is that it is a means of arranging elements according to their similar properties. This is what is meant by periodicity or periodic table trends.. There are multiple ways of grouping the elements, but they are commonly divided into metals, semimetals (metalloids), and nonmetals.
