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.
