Please correct me if I am wrong about the Magnesium atom. I can't find where I read this. Rozzychan 10:38, 25 July 2006 (UTC)


 * I do not find any evidence that says the electron that is excited comes from magnesium +2 ion. The third ionization of magnesium takes 80 eV.  Chlorophyll a and b take about 4 eV to ionize one electron.  The energy to strip an electron off of Mg+2 is twenty times that of a chlorophyll.  It is much more likely the electron comes from the pi electron cloud of the tetrapyrole.   224238scott (discuss • contribs) 23:16, 31 May 2023 (UTC)
