WebThe octet rule follows from the energetic favorability of having both the s and p subshells either completely empty or completely full. There is no p subshell in shell number 1, so that is part of why the lightest elements do not follow the octet rule (there are other reasons). WebJan 22, 2011 · How many shells in potassium?

WebThe atomic number of potassium is 19 Electronic configuration of Potassium : 1s^2 2s^2 2p^6 3s^2 3p^6 4s^1 Here the outer most energy shell is 4 & this shell contains only one electron. So, the number of valance electron of potassium is 1. Lobna Abdallah 7 y Originally Answered: How many valence electrons are in potassium ? WebAnd this is explained if we look at fluorine's valence shell (the second shell) electron configuration: 2s^ (2)2p^ (5). The second electron shell holds a maximum of 8 electrons and 8 electron would be considered a filled valence shell and would therefore be stable and unreactive. But fluorine has 7 valence electrons, 1 away from being filled. ons插件
