WebMar 11, 2024 · But there are total 14 valence electrons in P2H4 molecule (as calculated in step #1). So the number of electrons left to be kept on the central phosphorus atoms = 14 – 10 = 4. So let’s keep these four electrons (i.e 2 electron pairs) on the central phosphorus atoms. Now, let’s move to the next step. 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. WebA sodium atom contains 11 electrons orbiting a nucleus in 3 levels, 2 in the lowest, then 8, then 1 Sodium has 11 electrons.
