Chemistry - Liquids and Solids (32 of 59) Crystal Structure: Seven Types of Unit Cells

[@handmadesoap8327]

Very focussed on what does matter!! Super Fantastic!

[@febojarlock9469]

Brilliant explanation! But I have a silly question, why there are just 7 configuration? The combination of lengths (a=b=c, a≠b=c, a=b≠c, a=c≠b, a≠b≠c) and angles (x≠y≠z, x=y=z≠90, x=y=z=90, x=y=90, y=z=90, z=x=90... and so on) could give more configurations.

[@MichelvanBiezen]

You can interchange the x, y, and z, but you'll end up with the same thing if you place the crystal on each side or when you rotate it.

🙏🏻 thanks sir 🙏🏻

[@MichelvanBiezen]

Most welcome

[@ashleywoo2041]

Thanks for good explanation. i wasn't sure the difference between monoclinic and triclinic. But i understand better now. Thanks.

You are the best.

[@hudamh7479]

Gamma is the angle between a and c how come to be changed in the hexagonal shape you changed the location of gamma

[@MichelvanBiezen]

Gamma is still the angle between adjacent sides at the base. (gamma = 180 - 60)

You are The best indeed

[@legendarylife7515]

Tremendous lesson, thanks 🙏 for share it in this phenomenal way ✨✨🙏

[@MichelvanBiezen]

Our pleasure!

[@zulfiquarnadaf2082]

Sir your diagram and there measurements got interchanged among themselves (Respected fig. 2 and 3).

[@rishivanth5012]

nice Explanation sir

[@nazam8097]

So clear and explanatory. Thanks!

[@starofazure5597]

Yes, his explanation was......c r y s t a l clear.

[@jaapongeveer6203]

Yes but Michel how does the packing or atoms make a crystal a cube versus a tetragonal where only the c side is longer for example?

[@MichelvanBiezen]

How atoms pack into the various crystal shapes has everything to do with the actual structure of the atoms, the number of valence electrons, the electron orbitals, and the polarity of the atoms, and how the bonds are formed between the atoms and molecules.

Very good explanation thanks! ^^

Thank you

[@MichelvanBiezen]

You are welcome.

[@hr7cr7msd7]

Thank you but examples should also be there..

[@hr7cr7msd7]

How to distinguish whether primitive or body centered or face centered it is???

[@MichelvanBiezen]

Good suggestion. We cover that in detail in our chemistry videos on this channel, but we should also cover it here. Thank you.

[@hr7cr7msd7]

Thank you for the information🙏🙏

[@Truckshayari]

Thanks

[@bensonmonda9782]

Thank you so much !

[@hectornortey5980]

how do yuo draw planes in tetragonal structure

[@MichelvanBiezen]

+hector nortey The bond lengths are the same in 2 dimensions and different (longer or shorter) in the third dimension.

thank you so muchhh
