JEE Main Chemistry question

Which property increases in magnitude as the atomic number of alkali metals increases?

(A)Electronegativity
(B)First ionization energy
(C)Ionic radiusCorrect
(D)Melting point

Answer: (C)

Solution

Down group 1, as atomic number increases, electronegativity, first ionisation energy and melting point all decrease (A, B and D all decrease), since the valence electron becomes progressively easier to
