Unformatted text preview: and b) of Co. (a) The atomic number of Co is 27. How many unpaired d electrons are in a Co atom? ________ (b) Based on the number of unpaired d electrons of in a Co atom, how many Bohr magnetons per Co atom would you expect to contribute to the low temperature saturation magnetization of Co metal? (c) Determine the number of Bohr magnetons per Co atom contributing to the saturation magnetization at low temperature of sample b in the data shown below. [Note that 1 emu/g=1 A m 2 /kg; the density of Co is 8.86 g/cm 3 ; the atomic mass of Co is 58.93 g/mol; 2 24 m A 10 27 . 9 = B ....
