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

• As, fluorine has the smallest size among given elements and high nuclear charge and thus, fluorine is the most electronegative atom among atomic no. 9, 16, 18, 35.
• Also, electronegativity decreases down the group.
• Hence, fluorine is more electronegative than chlorine.
