Hi guys! In Electronics, silicon has 4 valence electrons.In order for it to be a crystal, each of these 4 valence electrons are paired with 1 valence electron from another silicon atom. Until such time that the outermost shell of an intrinsic silicon has 8 electrons all in all. I understand that silicon has 14 total electrons. Its electron configuration is 1s2-2s2-2p6-3s2-3p2. My questions are stated below:
Why cant there be 9 or any other number of electrons on the outermost shell of a silicon crystal?
Why does it have to be 8?
If 1s2 for example is to be rewritten as nMx, am i wrong to understand that 'x' is the number of electrons in every 'n' level? What does 'M' represent?
