NEET Chemistry Periodic Trends MCQ Question

Type: MCQ-conceptual-Hard-Class 11

Which of the following statements about periodic trends is correct?

A

Electronegativity increases across a period and decreases down a group.

B

Metallic properties increase across a period and decrease down a group.

C

Non-metallic properties are independent of electronegativity trends.

D

Atomic radii increase across a period from left to right.

Correct Answer

Option A

Detailed Explanation

Electronegativity does indeed increase across a period due to the increasing nuclear charge and decreases down a group as the atomic size increases, making it harder to attract electrons. This aligns with the NCERT context discussing the relationship between electronegativity and non-metallic/metallic properties.
