All the halogens require one more electron to complete a P-shell.
所有的卤素都要求得到一个额外的电子来填满p壳层。

So if we write the electron configuration you see that this is the electron configuration here, 1s22s22p 1 s 2, 2 s 2, 2 p 6, 3s1 and now we're going into that third shell 3 s 1.
现在我们来到第三层,你们会看到3s1价电子之间的区别，电子构型是，现在我们来到第三层。

Affected by the shell, the measuring accuracy of the FF-P sensing probe (with a metal shell) is quite different from a bared one, so calibration is needed.
