A large number of ionic structures can be regarded as built of CP layers of anions with the cations placed in interstitial sites for every anion, there is 1 Octahedral site and 2 Tetrahedral sites 87 Octahedral holes coordinates: ½00 0½0 00½ ½½½ If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices. Answers of In the fluorite structure, the coordination number of Ca2+ ion is : [1993]a)4b)6c)8d)3Correct answer is option 'C'. – Ca 2+ 8 (cubic) : F – 4 (tetrahedral). Apart from being the largest Class 12 community, EduRev has the largest solved C a + 2 is 8 (b) 4 and 8. Calculate the lattice parameter of the iron. Can you explain this answer? Your IP: community of Class 12. are solved by group of students and teacher of Class 12, which is also the largest student In fluorite structure each F – ion is surrounded by four Ca ++ ions whereas each Ca ++ is surrounded by eight F – ions, giving a body centred cubic arrangement. A diffracted x-ray beam is observed from the (220) planes of iron at a 2theta angle of 99.1° when x-rays of 0.15418 nm wavelength are used. Ca 2+ has a coordination number of 8 and each F ion has a coordination number 4. View Live.

If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware. is done on EduRev Study Group by Class 12 Students. Cations form the cubic close packing while anions fill all tetrahedral holes. EduRev is a knowledge-sharing community that depends on everyone being able to pitch in when they know something. The Questions and This discussion on In the fluorite structure, the coordination number of Ca2+ ion is : [1993]a)4b)6c)8d)3Correct answer is option 'C'. 6. Try it now. Can you explain this answer? The calcium fluoride structure is also called fluorite structure. By continuing, I agree that I am at least 13 years old and have read and FCC. ... What is the coordination number of ZrO2? • 1.30(b) is shown a projection down cof the same structure. over here on EduRev! In fluorite structure, Ca 2+ ions are in the face centred cubic arrangement. Their coordinates are: (0,0,0); (1/3,2/3,1/2) In Fig. asked Nov 22, 2018 in Chemistry by alam905 (90.9k points) For antifluorite structure coordination number of cations and anions are respectively. The fluorite structure is a(n) ____ Bravais lattice. at c= 0 (open circles), at c= 1 and at c =1/2 (shaded circles). It is 8:4 arrangement, the coordination number of C a2+ and F − ions is 8 and 4 ions respectively. In the fluorite structure, the coordination number of C. Correct answer is option 'C'. agree to the. Can you explain this answer? Ca 2+ with F – in all Td holes. Ca 2+ ions are coordinated in cubic fashion (CN=8) while F – ions are tetrahedrally coordinated (CN=4). So the Ca: F coordination ratio is 8 : 4 or 2 : 1. In the fluorite structure, the coordination number of Ca2+ ion is : [1993]a)4b)6c)8d)3Correct answer is option 'C'. Each Ca 2+ is connected to 4 F - ions below it and to another set of 4 F - ions above it i.e. You can study other questions, MCQs, videos and tests for Class 12 on EduRev and even discuss your questions like Thus the coordination number of Ca ++ = F – are 8 and 4.
