WebModern Periodic Table is based on the Modern Periodic Law which states that “The physical and chemical properties of the elements are the periodic function of their atomic numbers”. The elements are arranged in order of increasing atomic numbers in horizontal rows called periods and vertical columns called groups. WebIn a periodic table arranged in order of increasing atomic number, elements having similar chemical properties naturally line up in the same column (group). For instance, all of the elements in Group 1A are relatively soft metals, react violently with water, and form 1+ charges; all of the elements in Group 8A are unreactive, monatomic gases at ...
