Question

QI- Describe the enabling materials property of each of the following and why it is so:

 

(a) aluminum for airplane bodies.

 

b) nickel chromium for heating elements

All Questions cover S.L.O.I in ABET QI- Describe the enabling materials property of each of the following and why it is so: (a) aluminum for airplane bodies. b) nickel chromium for heating elements Q2- a) Compare and contrast metallic and covalent primary bonds and give one example in each bond. b) What type of bonding does KCI have? Fully explain your reasoning by referring to the electronic structure and electronic properties of each element. Q3- For the following elements : a) Mg, with Z = 12 b) S, with Z= 16 1- write electronic configuration 2- determine number of electrons in valance band 3- determine whether element is electropositive or electronegative element. Q4- The density of potassium, which has the BCC structure, is 0.855 g /cm^3. The atomic weight of potassium is 39.09 g /mol. (Avogadro number = 6.0221408x10^23 ) Calculate (a) the lattice parameter; and (b) the atomic radius of potassium. Q5- Define: mole, electropositive element, polymorphism, Anisotropy, Heisenberg's uncertainty principle. Q6 - Assuming that all of the valence electrons contribute to current flow, (a) calculate the mobility of an electron in copper and (b) calculate the average drift velocity for electrons in a 100 cm copper wire when 10 V are applied. Given( The lattice parameter of copper is 3.6151 10-", copper is FCC, o = 5.89 x 105)
