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?

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.
