a. How many unit cells share the center atom of the body-centered unit cell?
Answer:
b. How many total atoms are there in a body-centered cubic cell?
Answer:
c. What is the coordination number of the atom at the center of the body-centered
unit cell? How about the coordination number of an atom at the corner of this
unit cell? Coordination number is defined the number of nearest neighbors of an atom
or ion. Write also your answer in the summary table.
Answer:
d. Below is a body-centered unit cell, write the letter “a” along the edge length.
Calculate the length of the diagonal if all sides are "a". The dotted line refers to the
diagonal of the cubes body. (Hint: Use the Pythagorean relationship c²=a²+ b²)
