The process is similar to calculating an average grade. You can calculate the atomic mass of any element if you know the number of naturally occurring isotopes, their masses, and their percent abundances. 这与计算平均成绩的过程是类似的。如果你知道某一元素的各同位素的质量数,并且知道各同位素的丰度...
Carbon is taken as a standard element because there is no other element whose nucleus has a balanced number of protons and neutrons in it. How to Calculate Atomic Mass? The combined masses of protons and neutrons account for nearly all the mass of an atom, the atomic mass of a single ...
Knowing the relative fraction of each isotope of a particular element that occurs in nature allows you to calculate the atomic mass of that element, which, because it is an average, is not the mass of any one atom but a number that is between the heaviest and lightest isotopes pres...
