William Prout (1815) proposed that all other atoms are built up of hydrogen atoms, suggesting that all elements should have integral atomic masses based on an atomic mass of one for hydrogen. This hypothesis appeared discredited by the discovery of atomic masses, such as $24.3 \mathrm{u}$ for magnesium and $35.5 \mathrm{u}$ for chlorine. In terms of modern knowledge, explain why Prout's hypothesis is actually quite reasonable.
