How many electron shells does potassium have
WebFor example, potassium is in row four, so it has 4 electron shells. Placing the electrons on the shells Each shell can only hold a certain amount of electrons and each shell must be … WebSep 29, 2014 · Elemental potassium has an [Ar] 4s1 electron configuration. One would say it has one valence electron. If we take that one valence electron away, it makes sense to say that it now has zero valence electrons because "1 - 1 = 0".

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.
