Question

chlorine in the periodic table is surrounded by the elements with atomic number 9,16,18 and 35(b)which is more electronegative than chlorine?

Answer 1

oxygen => 16 a.m.u

O has 6 electrons on its outermost shell while Cl has 7 electrons on its outermost shell ,hence its easier for Cl to lose its 1 electron and complete the octet. Hence O is greater in electronegativity than Cl.
