How many atoms are in the following unit cells? Body centered cubic, face centered cubic (FCC), a hypothetical body centered/face centered cubic crystal, and a hypothetical diamond cubic structure with superimposed face centered cubic and body centered cubic atoms. Calculate the ratio of the packing factors for the following cases: simple cubic to face centered cubic. simple cubic to hypothetical face centered body centered cubic crystal (i.e. a face centered cubic with a similar atom placed in the center simple...
Identify the packing in the figure shown below. body-centered cubic cubic closest packed (face-centered cubic) hexagonal closest packed simple cubic
(a) Differentiate between Face- Centered Cubic (FCC) and Body-Centered Cubic (BCC) crystal structures. Why FCC metals are more ductile than BCC metals? 5 marks) (ii) show the relationship between the unit cell edge length, a, and the atomic radius, R, for a BCC crystal. Iron has a BCC crystal structure, an atomic radius of 0.124 nm, and atomic weight of 55.85 g/mol. Calculate its theoretical density Given: Avogardo's Number is 6.02 x 105 atoms/mol (5 marks) Figure 1 Determine the...
Rank the crystal lattice structures in order of decreasingefficiency of space in the structure. 1.Simple cubic 2.Body centered cubic 3.Face centered cubic 4.Hexegonal close packed I know simple cubic is the least effcient, and i figured itwhould be HCP-FCC-BCC-Simple cubic, but its not.. help please!! thanks
help question 4 (iv) For a simple cubic erystal Ano 0.43 836 74838, while for a face centered cubic crystal Aro 12.31 aad As 16.97. Which crystal structure is more strongly bound at equilibrium?5 Question 4 (25 marks) (i) Name any three properties of metals and expiain these on the basis of the classical free electron theory of metals (B) [7l (i) Describe the breakdown of the classicel theory of conduction in metals, and how the application of quantum mechanics...
11. (8 points) Give the answer to each question about solid state structures in the space provided. Remember to show your work. 240.7So Tungsten metal packs in the body-centered cubic (BCC) structure. If the body diagonal of the unit cell is 556 pm, what is the atomic radius of a tungsten atom? d-N30 24.hpm Nickel metal packs in the face-centered cubic (FCC) structure. If the body diagonal of the unit cell is 607 pm, what is the atomic radius of...
Post-lab question Part A 1. Metallic sodium forms a body centered cubic crystal. Why would the water displacement method used in part A not be suitable to determine the density of sodium? (Hint: watch the following video to help you answer this question: https://www.youtube.com/watch?v=18tOtZKpi04) 2. Calculate the density of sodium. (The radius of a sodium atom is 186pm) Post-lab Question Part B: Consider cubic array iodide ions (r =220pm) in which the anions are touching along the face of the...
please i need help with all questions 5. List the following cubic packing structures from least (1) to most (3) efficient structures (in terms of "packing efficiency"; be sure you can also sketch out the face and packing of these cubic structures, as well as calculate the packing efficiency of each one yourself. Do not simply memorize the packing efficiency values!) a. Simple Cubic b. Body-centered cubic c. Face-centered cubic 6. Calculate the mass of a single unit cell of...
1. Rank the crystal lattice structures in order of decreasingefficiency of space in the structure. Body centered cubic, face-centered cubic, simple cubic, hexagonalcubic. 2. ou are a researcher for a golf club manufacturer. You are giventwo identical looking cubes of a metal alloy. You are informed thatthey are made of the exact same material, but one is a crystalline,whereas the other is amorphous. It is your job to determine whichone is amorphous because this one is more stress-resistant and isuseful...
