The saturation magnetization of nickel measured at room temperature is 5.1×105 A/m.
(a) Calculate the average number of Bohr magnetons on a nickel atom, knowing that nickel has an FCC structure with an atom at 0,0,0. At room temperature the lattice parameter is 0.352 nm. (b) Compare your answer to part (a) with the theoretical number of Bohr magnetons based upon the atomic electron structure of nickel, and explain any possible difference.

It sure is bright everywhere; you've been able to travel around a bit, and it's clear that you are not in a star. Yet it is as bright as looking directly at the Sun
In your extensive travels through your current surroundings, you cannot find a single neutral atom anywhere, nor can you find a nucleus besides hydrogen or helium. And, while it is hot (a few thousand degrees Kelvin), it is nowhere near the temperature needed for nuclear fusion. Where are you? A) You are in the universe during its first 300,000 years. B) You are in the universe more than 10100 years in the future. C) You are in an accretion disk around a supermassive black hole. D) You are in the central regions of a quasar. E) You are where the Sun should be located, but about 5 billion years from now.
