NEET Chemistry Periodic Table MCQ Question
Which of the following statements about the periodic table is correct?
Noble gases have large positive electron gain enthalpies due to unstable configurations.
Elements in the same group exhibit different chemical properties due to varying atomic numbers.
The electron gain enthalpies are generally more negative towards the left of the periodic table.
The sixth period can accommodate 32 elements based on quantum numbers.
Correct Answer
Detailed Explanation
The sixth period of the periodic table is justified to have 32 elements based on quantum numbers, reflecting the arrangement of electron orbitals. Noble gases indeed have large positive electron gain enthalpies, but this is due to their stable configurations, not instability.
