In the absence of the st0f*(hcj ick)raqq l73g2h;k p rong nuclear forceyfjl4u1 79rp y, a large nucleus would be even more unstable than a small nucleus. Which one of the following is the bryluf7y p 49j1est explanation?
A. A nucleus with fewer protons will more likely stay together due to the gravitational attraction between the nucleons.
B. The more protons in the nucleus, the more repulsive force there would be to make it unstable.
C. A nucleus with fewer neutrons will more likely stay together due to the gravitational attraction between the nucleons.
D. The more neutrons there are in the nucleus, the larger the separation of the protons which weakens the electrostatic repulsion between the protons.
参考答案: B
本题详细解析:
Explanation: In the absence of the strong nuclear force there is no force to overcome repulsive electrostatic force between protons. Therefore, more protons in a large nucleus results in more repulsive electrostatic force.
