How to find the magnetic moment of a complex.
Asked by Gishin Rajan | 23 Feb, 2016, 08:29: PM
answered-by-expert Expert Answer
The formula to calculate the magnetic moment of a complex is:
begin mathsize 11px style straight mu equals square root of straight n left parenthesis straight n plus 2 right parenthesis end root BM Where comma straight mu equals magnetic space moment straight n space equals space number space of space unpaired space electrons BM space equals space Unit space of space magnetic space moment space left parenthesis Bohr space Magneton right parenthesis Example colon Let space us space now space caculate space the space magentic space moment space of space the space complex space left parenthesis NH subscript 4 right parenthesis subscript 2 MnBr subscript 4 space for space your space better space understanding. Here comma space in space this space complex comma space the space ammonium space group space adds space plus 2 space charge space and space hence space the space complex space becomes space left square bracket MnBr subscript 4 right square bracket to the power of 2 minus end exponent The space oxidation space number space of space Mn space equals space plus 2 The space electronic space configuration space equals space 3 straight d to the power of 1 The space number space of space unpaired space electrons space in space the space complex space equals space 1 Hence comma space substituting space the space above space values space in space the space formula comma space we space get comma straight mu equals square root of straight n left parenthesis straight n plus 2 right parenthesis end root space BM space space equals square root of 1 left parenthesis 1 plus 2 right parenthesis end root space BM space space equals square root of 3 space BM straight mu equals 1.73 space BM end style
