So we have a total of 2, 4, 6, 8, 10 valence electrons, so I'll make sure I count to 10 as we fill up our molecular orbitals here.

我们一共有2,4,6,8,10个价电子，所以我一边填一边要确认，我数到10。

Chemistry provides the bridge between the molecules of inanimate matter and the highly complex molecular architectures and systems which make up living organisms.

化学便在非生命物质的分子和组成活体组织的高度复杂的分子结构系统间架起一座桥梁。
