Question

32. Taking the example of an clement 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?​

Answer 1

Answer:

The electronic configuration of the element with atomic number 16 is 2,8,6. This indicates that the element belongs to group 16 and period 3 as the number of valence shell is 3 and valence electrons is 6. ... If the valence electrons are less than or equal to four then the valency is the number of valence electrons.
