NEET Chemistry Atomic Radius MCQ Question
Which of the following combinations accurately describes the atomic radius and its measurement?
The atomic radius can be measured precisely by determining the bond distance in a covalent molecule, and the covalent radius is half this distance.
The atomic radius is determined solely by the number of protons in the nucleus, making it easy to measure.
The atomic radius is defined as the distance from the nucleus to the outermost electron, which has a sharp boundary.
Covalent radius can be estimated from the distance between atoms in a covalent bond, but cannot be calculated from ionic radii.
Correct Answer
Detailed Explanation
The atomic radius can be estimated by measuring the distance between atoms in a covalent molecule, and the covalent radius is calculated as half of this distance, as stated in the NCERT context.
