NEET Chemistry Periodic Trends MCQ Question
Which of the following combinations regarding periodic trends is correct?
Electronegativity increases across a period and decreases down a group.
Metallic character increases across a period and decreases down a group.
Non-metallic properties increase down a group and decrease across a period.
Ionization energy increases down a group and decreases across a period.
Correct Answer
Detailed Explanation
Electronegativity is known to increase across a period due to increased nuclear charge and decreases down a group as the distance from the nucleus increases. This reflects the relationship between electronegativity and metallic/non-metallic properties.
