Post-lab Questions Part 2 8. Among the elements, hydrogen has the least massive atoms. An atom of hydrogen has an average mass of 1.66 x 10-24 g. This mass is very small, but remember it is only one atom which is composed of one proton and one electron! What is the relative mass of hydrogen if it is the least massive element? 9. How do the atomic masses found on the periodic table compare to the relative masses you calculated?...
