Solution: Why does the band of stability curve upward at high atomic numbers? A. Excess neutrons are required due to the repulsion between the protons. B. If we have too many protons, not enough electrons will be orbiting the atom to keep it electrically neutral overall. C. Excess protons are required to help keep the neutrons from sticking together as neutrons have no charge. D. Atoms with high atomic numbers have a large number of electrons orbiting the nucleus. This increased number of electrons requires a lot of extra mass in the nucleus to keep the electrons in their orbit.

Problem

Why does the band of stability curve upward at high atomic numbers?

A. Excess neutrons are required due to the repulsion between the protons.

B. If we have too many protons, not enough electrons will be orbiting the atom to keep it electrically neutral overall.

C. Excess protons are required to help keep the neutrons from sticking together as neutrons have no charge.

D. Atoms with high atomic numbers have a large number of electrons orbiting the nucleus. This increased number of electrons requires a lot of extra mass in the nucleus to keep the electrons in their orbit.
