JEE Main Chemistry question

In the third row of the Periodic Table, from Na to Cl

(A)Electronegativity increasesCorrect
(B)Electronegativity decreases
(C)Ionisation energy decreases
(D)Atomic volume increases

Answer: (A)

Solution

Moving from Na to Cl across period 3, nuclear charge increases while atomic size decreases, both of which strengthen the atom's hold on electrons. As a result, electronegativity
