The atomic numbers of two elements are 8 and 16 respectively. Write the electronic configuration of these two elements. Do you keep these two elements in the same group of the modern periodic table? Justify your answer. Find out which of these two elements is more electronegative. Give reason for your answer.

Explanation

Atomic number: 8
Electronic Configuration : 2, 6
Atomic number: 16
Electronic Configuration : 2, 8, 6
Same number of valence electrons therefore in the same group.
Electronegativity is the tendency of an atom to attract shared pair of electrons towards itself.
Electronegativity decreases down the group. Therefore, oxygen is more electronegative than sulphur.
