Question

Which group 16 element is the most electronegative?

(a) Sulphur

(b) Polonium

(c) Oxygen

(d) Selenium

This question was posed to me in class test.

I'm obligated to ask this question of P-Block in section P-Block Elements of Chemistry – Class 12

Answer 1

Right answer is (c) Oxygen

For explanation I would say: The elements of group 16 have higher values of electronegativity than the corresponding elements of group 15. Actually, oxygen is the second most electronegative element (EN=3.5), the first being fluorine (EN=4.0).
