The chemical properties of elements are periodic to atomic numbers. The elements in the periodic table are arranged in order of increasing atomic number. All of these elements display several other trends and we can use the periodic law and table formation to predict their chemical, physical, and atomic properties.Metalic properties ,while moving in period decreases and nonmetalic properties increases upto seventh group. Chemical reactivity going down in group for metals increases . These are few examples , understanding these trends is done by analyzing the elements electron configuration; all elements prefer an octet formation and will gain or lose electrons to form that stable configuration
