Question

Light elements with Z < 20 generally have a neutron/proton ratio about equal to ________

Quizplus · Accepted Answer

For light elements with Z < 20, the neutron/proton ratio is generally about equal to 1. This is because the repulsive electromagnetic forces between protons in the nucleus are balanced by the attractive strong forces between protons and neutrons. As the atomic number increases, heavier elements tend to have more neutrons than protons to maintain stability.
