Taking the example of an element of atomic number 16, explain how the electronic configuration of the atom of an element relates to its position in the

modern periodic table and how valency of an element is calculated on the basis of its atomic number.


If the Atomic No of the Element Is 16 so its electronic configuration is 2,8,6 so it has 3 shells or orbits so it belongs to period 3 bcoz of having 3 shells then its valence shell [Last shell] has 6 electrons so it belongs to group IV - A (which is now called Group 16) hope u Understand. if any doubts or problems regarding to dis plz consult me
