Type: MCQ-conceptual-Easy-Class 12
Which of the following statements about nuclear density and atomic mass are correct?
A
Nuclear density is much larger than the density of ordinary matter.
B
Most of the atom is filled with nucleons.
C
Nuclear forces are strongly repulsive at very short distances.
D
Binding energy is not relevant in nuclear reactions.
Correct Answer
Option A
Detailed Explanation
Nuclear density is indeed much larger than that of ordinary matter, as indicated in the NCERT context. Most of the atom consists of empty space, which contradicts option B. Although nuclear forces can be repulsive at short distances, they are primarily attractive, making option C incorrect. Binding energy is crucial in nuclear reactions, which makes option D incorrect.
