What is the noble has gas with the lowest atomic mass?
Helium with an atomic mass of 4.00260
Gas atomic mass 16 8 nuetrons?
The number of protons and neutrons in an atom is equal to its atomic mass. Since the atomic mass of this gas atom is 16 and it has 8 neutrons, the remaining mass (16-8=8) must be the protons in the nucleus. Therefore, this gas atom has 8 protons.
