When the elements are thus arranged, there is a recurring pattern called the ‘periodic law’ in their properties, in which elements in the same column (group) have similar properties. 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. 4 Periodic Law = elements in periodic table are PERIODIC functions of their ATOMIC NUMBER 1) As you move down a GROUP or COLUMN, you add 1 PRINCIPAL ENERGY LEVEL or ELECTRON SHELL 2) As you move across a ROW or PERIOD, you add 1 PROTON to the nucleus, and 1 ELECTRON to the VALENCE SHELL 3) The MAXIMUM number of VALENCE ELECTRONS any element can have is EIGHT, therefore … But there are usually trends in properties that allow us to make predictions.
