23/10/2017· Fluorite, CaF 2, having twice as many ions of fluoride as of calcium, makes use of all eight tetrahedral holes in the CPP lattice of calcium ions (orange) depicted here. To help you understand this structure, we have shown some of the octahedral sites in the next cell on the right; you can see that the calcium ion at A is surrounded by eight fluoride ions, and this is of course the case for
Which one of these diagrams represents a pure metal?Diagram b is a pure metal – the atoms are arranged in a regular lattice. Whenpressure is applied (by hammering the metal) the layers can slide over eachother – this is why metals are malleable and ductile.But when the metal is an alloy (diagrams a, c, and d) new atoms enter thelattice and the layers can no longer slide easily.

2/4/2018· Ionic lattices are variations of the metal lattice structures. If a close packed metal lattice structure is adopted by one type of ion and some or all the tetrahedral or octahedral sites are occupied by ions of opposite charge, an ionic lattice is formed. In a sodium
This is the structure adopted by Calcium Fluoride, CaF 2. There is now an fcc array of calcium ions, and the fluoride anions occupy all of the tetrahedral holes. There are two tetrahedral holes for each atom in the fcc array, and so the stoichiometry of the compound dictates that both of the tetrahedral holes be occupied for each of the ionic fcc sites.
