How Is The Periodic Table Used To Determine The Properties Of Elements? Determining Chemical Properties using the Periodic Table. Chemical properties of each element are determined by the element’s electronic configuration, and particularly by its outermost valence electrons. … In addition, the total number of electron shells an atom determines which period it belongs to.
How Does The Periodic Table Of Elements Help Scientists Today? Now, the table is useful for modern students and scientists because it helps predict the types of chemical reactions that a particular element is likely to participate in. … The table tells each element’s atomic number and usually its atomic weight. The typical charge of
