1.	Ionisation energy of atoms A and B are 350 and `250 kcal mol^(-)` respectively. The electron affinities of these atoms are `70 kcal mol^(-1)` and `90 kcal mol^(-1)` respectively then:A. Electron cloud is more attracted by AB. Electron cloud is more attracted by BC. Electronegativity of A is more than BD. Electronegativity of A is less than B
Answer» Correct Answer - A::C `E.N_(a) prop 350 +70, E.N_(B) prop 250 +90` `rArr E.N_(A) gt E.N_(B)`
