Modern periodic law is the base of periodic trends of properties of elements in the modern periodic table. Periodic Trends of Properties of Elements In Periodic Table
In this article, we will discuss periodic properties and their trends in the periodic table in detail. Periodic trends provide chemists with a quick and easy tool to quickly predict the properties of elements. Thus, we can say that elements having similar electronic configurations have similar properties. The recurrence of similar electronic configuration in the periodic table is the cause behind periodicity. The following figure shows the variation of periodic properties of elements.Īlthough we find some exceptions which do not follow these periodic table trends. For example, as we move from left to right in a period, atomic size decreases. That’s why elements show periodicity in their physical and chemical properties in the periodic table. In the modern periodic table elements have been arranged according to their atomic numbers and as stated above atomic numbers are directly related to their physical and chemical properties.

So the upper left hand elements have the most protons within their respective period with which to generate pull on the electrons. The electrons will not be any further away from the than the previous element but there will be one more proton with which to generate attractive force on the electrons. As one moves from left to right within the same period, one electron and one proton are added to each element. Conversely, the nuclei of the elements in the lower left hand side of the periodic table exert the weakest attractive force on their electrons when compared to the other elements. Flourine is the most electronegative element because the positive charge of its nucleus exerts the strongest attractive force on it's electrons when compared to the other elements.
This is because of the changes in the atomic radii of elements that occurs as one move in these directions. Electronegativity increases as one moves left to right across the periodic table, it also increases as one moves up the periodic table.
