THIS USER ASKED ๐Ÿ‘‡

For light elements, what is the ratio of neutrons to protons that predicts a stable nucleas? 10: 5 2: 1 1: 1 1.5: 1

THIS IS THE BEST ANSWER ๐Ÿ‘‡

For most elements in phases 1 and 2 (the light ones), the mass of the stable nuclei is 2 times greater than the atomic number, thus the number of neutrons is the same as protons, so the nuclei are stable genetic neutron: 1: 1 proton content.
I hope this helps.
