Discussion:
Radius/Density From bcc and fcc Unit Cells
Krypton crystallizes as a fcc (face centered cubic unit cell) having an edge length of 559 pm.
(a.)What is the density of solid Krypton?
(b.) What is the atomic radius of a krypton atom?
(c.)What is the volume of one krypton atom?
2. Potassium crystallizes in a bcc (body centered cubic unit cell) structure. The atomic radius of potassium is 235 pm. Determine:
(a.) the number of atoms of potassium per unit cell, and
(b.) The length of a side of this unit cell.
Draw a pressure temperature curve for Sulfur Dioxide. Detail the areas where the material exists as solid, liquid, and as a gas. Explain what is meant by critical point, triple point, and critical temperature
