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?
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.
Plz Halp! Where can I get the periodic data files to create supercells in chemdoodle? I really want to make it work on my machine! Thanks in advance for any advice!!!
Ever since I saw you "Destroy Kent Hovind", you have been my first choice for all chem/bio/calc study videos!
i think when you are able to visualise the whole thing it becomes easier to understand, thanks sir
Thanks for a lot of these videos, they have been really helpful.
Wow this helps me understand the difference between ionic and covalent bonds! Lattice structures vs. molecules.
Thnx profff dave plz upload a video for calculation of fcc and bcccompounds in solid state
Really good!

was thinking the same thing. I was taught half the tetrahedral holes were filled in the zinc sulphite structure.

DADDDYYYYSS HOMEEE
Thanks, very good video!
Thank you!
Very helpful thx sir
What type of program you use?
Nice sir

That was perfect! Really help, sir.
ABAB packing vs ABCABC packing .
the tetrahedral structure of ZnS looks just like that of a diamond🤔
They are same
can someone make me a description for polonium

"It's very affordable." $750 lifetime licence. Yes, seven-hundred-and-fifty US Dollars.
Great video though, thanks.
No ChemDoodle is way cheaper than that, I'm not sure where you got that info.
@@ProfessorDaveExplains From the link you provided. $15 per month or $150 per year or $750 lifetime.
Weird, I thought it was less, maybe they changed it.
omg your telling me he wasnt always jesus?
Sir did u take a hair cut
I miss your hair
