A powder company is hiring you as an intern researcher. Currently they are using a standard powder for their application and, according to the manufacturer specification, one sphere particle of 10 microns in radius has 2.03x1014 atoms A group of R&D engineers claim that the performance of the powder will improve only if there are four times the number of atoms in each 10-micron radius particle compared to the current standard powder, They proposed nickel (Ni) as an alternative material. It has the FCC crystal structure and atomic radius of 0.149 nm. They asked you to prove or disprove their claim. Assume a single perfect crystal in the particle for both the standard and the alternative materials. Hints: • This problem can be solved in two different ways, pick one (or try both to check your answer if you have time). • You need to work on the alternative material, then compare the final value with the proposed claim. • (1) a particle is a sphere, (2) an atom is a sphere, (3) a unit cell is not a sphere. Each way of solving needs only 2 out of these 3.

What do you predict will be the outcome of their experiment? O A The ferrofluid will function normally because magnetite particles will still be formed. . B. The resulting product will not exhibit magnetic properties. O C The magnetite particles will precipitate out instead of remaining suspended. O D. The particies formed will be too small and the ferrofluid will not form spikes.
