- abstract:
1 Carbon-12 is the more abundant of the two stable isotopes of the element carbon, accounting for 98.89% of carbon; it contains six protons, six neutrons and six electrons.
- 1
Over time, that carbon-14 will decay to regular carbon-12. - 2
Molecular weight: Mass of a molecule of a substance, Based on 12 as the atomic weight of carbon-12. 分子量：物质的分子质量，依据的事实是1莫耳的碳- 12的质量是12克。 - 3
Carbon dating works by comparing the amount of carbon 14, which is a less common and less stable form of carbon, to the more abundant carbon 12. 碳的年代测定工作是将碳14(碳处于这种状态并不常见，也不稳定)与碳12(碳的常见状态)的含量进行对比。
