NEET Chemistry Periodic Trends MCQ Question
When moving from left to right across a period in the periodic table, which of the following properties generally decreases?
Atomic radius
Electronegativity
Non-metallic character
Ionization enthalpy
Correct Answer
Detailed Explanation
According to the NCERT context, as we move from left to right across a period, the atomic and ionic radii generally decrease. This is due to the increased nuclear charge attracting the electrons closer, resulting in a smaller size.
