iron ions?
does iron lose 2 electrons even though this does not give it a stable valence shell for iron 2
does iron lose three electrons even though this does not give it a full valence shell if so why because as far as i know if an element loses electrons it only loses electrons if it is possible to end up with a full valence sheel depending on the circumstances
Thanks david i will ceratainly look out for this sort of thing i am still a student thos so thanks for the help

does iron lose 2 electrons even though this does not give it a stable valence shell for iron 2 ==== Yes it is losing 's' sublevel electrons == just like calcium or magnesium losing 's' electrons == these are in the outermost energy level and are the most unstable
does iron lose three electrons even though this does not give it a full valence shell if so why because as far as i know if an element loses electrons it only loses electrons if it is possible to end up with a full valence sheel depending on the circumstances
-- loses 2e- from the outermost 's' and ONE extra electron from a 'd' sublevel. --- this creates more stability === you are trying to apply rules for the group 1 and 2 elements which have no d electrons to worr with === when the 'd' is 1/2 full this creates more stability than the element when unreacted... You might learn this later in the book.
