How do you find the valency of an element?
Mathematically we can say that if the outermost shell of an atom contains 4 or less than 4 electrons, then the valency of an element is equal to the number of electrons present in the outermost shell and if it is greater than 4, then the valency of an element is determined by subtracting the total number of electrons …

How to find the trend of Valence in periodic table?
Click on ‘Element Atomic Number’, ‘Element Symbol’, ‘Element Name’ and ‘Element Valence’ headers to sort. Loading, please wait… In the below periodic table you can see the trend of Valence.
The valencies of the elements belonging to the s-block and the p-block of the periodic table are generally calculated as the number of valence electron or eight minus the number of valence electrons. For the d-block and f-block elements, valency is determined not only on the basis of valence electrons but also on d and f orbital electrons.
