How many electrons are in se
WebNov 11, 2010 · Ok if you look at the Periodic Table Se is in 3P4. So you know that P can hold up to 6 electrons. In your mind picture three boxes and each box holds two electrons, But … 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.
