How many atoms are there per unit cell in polonium, tungsten, and nickel? In the unit cell of polonium, there are eight atoms located at the corners of the cell (one eighth in and seven eighths out). Tungsten's unit cell consists of one atom in the center and eight atoms at the corners (one eighth in and seven eighths out). Nickel's unit cell contains six atoms within the faces of the cell (half in and half out) and eight atoms at the corners of the cell (one eighth in and seven eighths out). Provide the number of atoms per unit cell for polonium as an integer.
