Question

33.
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.​

Answer 1

8 = 2,6     16 = 2,8,6   both these elements are oxygen and silicon repecticvely and kept in the same group(16th) . 6 - (oxygen) is more electronegative, because on going down in a group the electronegativity decreases.                                                         ( as we go down in a group in the periodic table one more electron shell is added to the atom at every step and the size of atom goes on increasing. due to this increase in size, its nucleus goes deep inside the atom. the attraction for the incoming atom decreases due to which the atom can't form negative ions easily and the electronegativity character decrease)

Answer 2

Explanation:

oxygen is more negative element than the 16th element sulphur
