How many energy shells does potassium have

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?

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 https://craniosacral-east.com
