JEE Main Chemistry question

Point out the wrong statement. On moving horizontally from left to right across a period in the Periodic Table

(A)Metallic character decreases
(B)Electronegativity increases
(C)Gram atomic volume first decreases and then increases
(D)Size of the atoms increases for normal elementsCorrect

Answer: (D)

Solution

Across a period, effective nuclear charge increases while the number of shells stays the same, so the atomic radius of normal (representative) elements actually decreases, not increases, making statement (D) wrong. Metallic character correctly decreases (A), electronegativity
