WebWhy is it that the names of isotopes only change by number, but the element name remains the same (for example, isotopes of hydrogen include hydrogen-1, hydrogen-2, and hydrogen-3)? Part Two: Mass Number 4) Describe what happens to the mass number of an isotope (shown on the scale) when you change the number of neutrons in the atom’s … WebIn 1803 John Dalton proposed to use the (still unknown) atomic mass of the lightest atom, that of hydrogen, as the natural unit of atomic mass. This was the basis of the atomic weight scale. For technical reasons, in 1898, chemist Wilhelm Ostwald and others proposed to redefine the unit of atomic mass as 1 ⁄ 16 of the mass of an oxygen atom.
