Structure of Sodium Chloride (NaCl)

Sodium chloride crystal is made up of sodium and chloride ions. Sodium chloride crystal has a face-centered cubic close packed structure.The chloride ions occupy the corner and face centered positions, the sodium ions occupy the octahedral voids in cubic close structure.The unit cell of NaCl contains 4 chloride ions and 4 sodium ions. The coordination number of sodium chloride is 6.

First of all for the love of god stop saying AYONS

Simple and Superb Explanation Video Mam 🙂. Upload more videos Mam.

One who already knows it can understand it better!!!

[sohelmondal]

Then what will be the value of Z, to calculate the density of the cell?

[sandeeppatil]

Mam why na does not create tetrahedral voids ???

[ASHOKKUMAR-cxey]

Lekin fcc ka to coordination number 12 hota hai na ????

[maybedont]

If the valency of both na and cl is 1 how can they have like 6 atoms surrounding them, they can only have 1 bond

[yogeshkumar-yyzz]

why each cl ions is surrounded by Six Na ions and why it is not surrounded by four ions can any one tell me 🙂🙂🙂🙂🙂🙂

[TempleSquire]

Its actually very informative, its not accent but words and phrases that often make accents hard to grasp as even in native English speakers use different words, specifically in science.

This was too useful and helpful to imagine... thank you

Oh man this made so much more sense. Thank you! For those of you who can't get past the accent I'll summarise it for you.
So the Cl being anions are bigger and will occupy the corners and faces which is going to result in 3 layers (draw it out and you will see it). The Na being smaller will fill octahedral holes, the one in the center and between the edges of each layer, because each Cl is surrounded by 6 Na atoms and 1 Na atom is surrounded by 6 Cl atoms hence making the coordination number 6:6. So to calculate; There is one Na in the center and 12 edges x ¼ in each layer = 1 + 3 = 4 cations. For anions its 8 x 1/8 corners + 6 faces x ½ of the sphere of each face = 1 + 3 = 4 anions.

You're supposed to push the button with food on it

[pratikchoudhuri]

At last I understand fully about Nacl structure, thanks a lot...

[ladfromkarak]

why Na is smaller in diagram despite its atomic size greater than Cl

[ASHOKKUMAR-cxey]

But we were told that the coordination number of a fcc lattice is always 12. Am i wrong ???

[amanjaiswal]

Thanks this video is very helpful to us to understand NaCl

[youtuber-nxen]

Thank Youu so much for this video. It was so very helpful. ❤️❤️❤️❤️

[Taha.]

ur pronouncing of anions and ions is so bad 😳

[kalamii_]

The indian accent is really cringey and distracting.... I just want to sweeeeaaaarrr!!!
