Question

Which of the following statement is incorrect? (A) Electron affinity of nitrogen and noble gases is zero (B) Cesium is the most electropositive element; while fluorine is the most electronegative element (C) Chlorine has the highest electron affinity among all the elements of periodic table (D) In any period, the atomic radius the noble gas is lowest

Tardigrade Admin · Accepted Answer

Atomic radius of helium is greater than H. Similarly, atomic radius of neon is greater than that of fluorine. This is because interelectronic repulsion in fully-filled shells outweighs the effect of increased effective nuclear charge. Rest statements are correct.
