amit Posted February 6, 2008 Posted February 6, 2008 why magnesium shows +2 state why dont it settle for +1. energy for +2 is 5 times higher
insane_alien Posted February 6, 2008 Posted February 6, 2008 because it is more stable when it is in the +2 oxidation state than the +1 state because it would then have a full shell on the outside. +1 states do exist but never for long(we're talking femtoseconds here).
thedarkshade Posted February 6, 2008 Posted February 6, 2008 That's because it has two electrons in the outer shell. Its his fundamental chemical characteristic, just like sodium +1, fluorine -1, potassium +1 etc!
