- The compound gallium arsenide is a commonly used semiconductor,having an energy gap Eg of 1.43 eV. Its crystal structureis like that of silicon, except that half the silicon atoms are replacedby gallium atoms and half by arsenic atoms. Draw a flattened-outsketch of the gallium arsenide lattice, following the pattern.What is the net charge of the (a) gallium and (b) arsenic ioncore? (c) How many electrons per bond are there? (Hint: Consultthe periodic table in Appendix G.)In XCI, which crystallizes in NaCl structure, the sum of the anionic and cationic radii is found to be 296 pm. The density of the compound is 4,591 g cm3. Calculate the mass of the cation as g mol! Do not write units, only enter numerical values. Use two digits at most for decimal numbers, use dot (.) as decimal separator (i.e. two-point-fifty-one should be entered as 2.51). Do not use comma (,) as decimal separator. Answer: 143.4How many lattice paths are there from the point (−3, 10) to the point (5, −2) if the pathwaymust only go right and up?
- Q#02. Answer the followings: (a) Elucidate the salient features of reciprocal lattice and how does it help to investigate the crystal structures.The rutile and fluorite structures, shown here (anions arecolored green), are two of the most common structure typesof ionic compounds where the cation to anion ratio is 1 : 2.(a) For CaF2 and ZnF2 use ionic radii, Ca2+ 1r = 1.14 A° 2,Zn2+ 1r = 0.88 A° 2, and F- 1r = 1.19 A° 2, to predict whichcompound is more likely to crystallize with the fluoritestructure and which with the rutile structure. (b) What arethe coordination numbers of the cations and anions in eachof these structures?The table below shows some physical properties of halogenatedliquids.Which of the following statements best explains these data?(a) The larger the dipole moment, the stronger the intermolecularforces, and therefore the boiling point is lowest for themolecule with the largest dipole moment. (b) The dispersionforces increase from F to Cl to Br; since the boiling point alsoincreases in this order, the dispersion forces must make a fargreater contribution to intermolecular interactions thandipole–dipole interactions. (c) The trend in electronegativityis F 7 Cl 7 Br; therefore, the most ionic compound 1CH2F22has the lowest boiling point, and the most covalent compound1CH2Br22 has the highest boiling point. (d) Boiling point increaseswith molecular weight for these nonpolar compounds.
