NH4Cl
|`````````H
|`````````..```````````..
|````[``H:N:H``]+```[`:Cl:`]`-
|`````````..```````````..
|`````````H
PH3
|`````````H
|`````````..
|```````H:P`:H
|`````````..
C2H6
|```````H``H
|```````..`..
|`````H:C:`C:H

|```````H``H
HF
|`````````..
|``````H:`F`:
|`````````..
MgO
|````````````..
|`````Mg2+`[:O`:]2-
|````````````..
BaCl2
|````````..```````````..
|``````[:Cl:]-`Ba2+`[:Cl:]-
|````````..```````````..

单原子电子式打点的顺序参照这个:
|```````````````````.`````.````.````..````..
|```Li.``Be:``.B:``.C:```.N:``:O:``:F :``:Ne:
|`````````````````````````.````.````.`````..
规则是:
1 1
2 2
3 2+1
4 2+1+1
5 2+1+1+1
6 2+2+1+1
7 2+2+2+1
8 2+2+2+2
拷贝下来,然后把"`"换成" "再看
