Consider the FCC and HCP closed packed structures in units of ro, the radius of the close-packed atom. Explain why there are no common HCP based ionic structures with all of the octahedral sites filled or all the tetrahedral sites filled. Use Pauling’s rules and your knowledge of the ABAB and ABCABC stacking sequence to answer the question.
Homework Answers
The packing fraction of hcp is 0.76. In ABAB type of packing regular hexagon is formed that and has vacancy of 24%while the no of octahedral void is same as zeffective whereas the no of tetrahedral void is twice the zeffective size of tetrahedral void is less than the octahedral void.

Q: Compare the assumptions of physician-centered and
collaborative communication. How is the caregiver’s role different
in each model? How is the patient’s role different?
Answer: Physical-centered communication involves the specialists
taking control of the conversation. They decide on the topics of
discussion and when to end the process. The patient responds to the
issues raised by the caregiver and acts accordingly. On the other
hand, Collaborative communication involves a...
