例如，布基球的原子键是一种独特的球面结构，球面中有六边形也有五边形(就和足球一样)，碳原子位于顶点处。

Buckyballs, for instance, have a unique spherical structure of atomic bonds that create a hexagon-pentagon structure (like that of a soccer ball) with atoms residing at the vertices.

And so you can look, for example, at the Periodic Table And, if you look up the atomic mass of carbon, 011 you will see that carbon comes at 12.011 for carbon.

如你们所见，例如，在周期表中,如果你观察碳的原子质量，你会看到是12。
