NEET Chemistry Periodic Trends MCQ Question
Which of the following statements about periodic trends is correct?
Atomic and ionic radii generally decrease from left to right across a period.
Electronegativity increases down a group due to increased shielding.
Chemical reactivity of non-metals decreases across a period.
Ionization enthalpy decreases as you move down a group.
Correct Answer
Detailed Explanation
Atomic and ionic radii generally decrease from left to right across a period due to increasing nuclear charge, which pulls electrons closer to the nucleus. This is a fundamental periodic trend described in the NCERT context.
