The properties of a given metal are greatly dependent upon the way in which the atoms are arranged. A unit cell is like a "zoomed-in" view of a substance that allows us to see the basic pattern of the arrangement of atoms. In this problem you will study several types of cubic arrangements: the simple cubic, (Figure 1) the face-centered cubic, (Figure_2) and the body- centered cubic.(Figure_3) Bismuth is a nontoxic metal that is used in pharmaceuticals and chemicals. Bismuth has a simple cubic unit cell. How many atoms of Bi are present in each unit cell? Express your answer as an integer. Gold has a face-centered cubic unit cell. How many atoms of Au are present in each unit cell? Express your answer as an integer. Iron has a body-centered cubic unit cell. How many atoms of Fe are present in each unit cell? Express your answer as an integer.
