i think when you are able to visualise the whole thing it becomes easier to understand, thanks sir

Wow this helps me understand the difference between ionic and covalent bonds! Lattice structures vs. molecules.

6:44 we were taught that in the structure for CaF2, the fluoride ions will fill all (ie. 100%) the tetrahedral voids/ holes. i cross checked my notes with my textbook and it says the same thing..... so why did you say half?
@sampower5106 2 жыл бұрын
was thinking the same thing. I was taught half the tetrahedral holes were filled in the zinc sulphite structure.

Look at the picture. The single tetrahedron has one interior tetrahedral hole. On each face it has another hole which is shared with one other. So that's six more that count as half each, or three. Four holes. But it only has two fluorides to put in them.

No ChemDoodle is way cheaper than that, I'm not sure where you got that info.
