Question
What makes a nucleus stable?A.A nucleus is stable if the electrostatic and strong nuclear forces balance out.B.A nucleus is stable if there are fewer neutrons than protons in the nucleus.C.A nucleus is stable if there is the same number of protons as electrons.D.A nucleus is stable if all of the electrons are in the lowest energy levels.
Solution
The stability of a nucleus is determined by the balance between the electrostatic and strong nuclear forces. This is option A.
The electrostatic force is the force that causes protons to repel each other because they all have the same positive charge. The strong nuclear force, on the other hand, is the force that holds the protons and neutrons together in the nucleus.
When these two forces are in balance, the nucleus is stable. If the electrostatic force becomes stronger than the strong nuclear force, the nucleus can become unstable and decay.
Options B, C, and D are not correct. The number of neutrons compared to protons can affect stability, but a stable nucleus does not necessarily have fewer neutrons than protons. The number of protons compared to electrons does not affect nuclear stability, as electrons are outside the nucleus. The energy levels of the electrons also do not affect nuclear stability.
