Their masses, based on the carbon scale, are 10.01 and 11.01, respectively. The ion of m/z = 50 has a relative abundance of 30%, meaning the mass spectrum contains 30% as many ions of m/z =50 as m/z = 30 (the base peak). The abundance of elements in the Sun and outer planets is similar to that in the universe. Abundance differs from excess in that a reactant in excess is simply any reactant other than the limiting reagent; the amount by which a reactant is in excess is often specified, such as with terms like "twofold excess", indicating that there is . Deuterium is frequently represented by the chemical symbol D. Since it is an isotope of hydrogen with mass number 2, it is also represented by 2 H. IUPAC allows both D and 2 H, although 2 H is preferred.
