then you can explain periodicity

我们也能够解释
and see why some atoms give up an electron to lose the outer shell

为何有的原子会失去单电子的最外层
and others gain one to complete the outer shell.

而有原子会把最外层的8个电子凑齐
Okay, so but it also could explain how you get bonding,

这个理论同样能解释化学键的产生
if you like to have octets;

用八偶体的理论
not just electron transfer but the formation of covalent bonds.

可同时解释电子转移和共价键的形成
So, for example, here's two chlorines.

拿两个氯原子来举例
Each has only seven; the octet isn't complete.

它们的最外层分别缺1个电子
But if you bring them together and they share an edge,

但如果将它们拼在一起共用一条边
then both octets are complete.

这两个立方体的8角结构就都完整了
He doesn't say why octets should be so great,

他并未解释为何八角立方体会如此神奇
but if they're octets

但若果真如此
