18. Why is the neutron to proton ratio so important? Scientists made up this concept because they wanted to create radiation. An atom's nucleus likes to have the same number of neutrons and protons, so knowing that ratio is important. It determines the stability of the nucleus based on the shielding effect of the neutrons. The neutron to proton ratio describes a radioactive element's half-life. hp esc @ # $ &. 1 2 4. W e r y tab 10
