Question

Our bodies are mostly made of hydrogen (z = 1), carbon (z = 6), and oxygen (z = 8). in our bodies, are there many more neutrons than protons, many fewer neutrons than protons, or are there about the same number of each?

Answer 1

In their common forms, both carbon and oxygen have an equal amount of protons and neutrons, 8 and 6 respectively, while hydrogen has one proton and no neutrons. Since there is far less hydrogen than carbon or oxygen, there should be more protons than neutrons, but not by a lot.
