Thank you sooooo much ma’am. Thank you very much , your way of teaching is very simplified and easy . I have seen many videos but never understood it and every time I wrote wrong answer in paper and have come empty handed . Thank you soo much maam
Which set of following characteristics for ZnS crystal is correct? (a) Coordination number (4 : 4); ccp; Zn⁺⁺ ion in the alternate tetrahedral voids (b) Coordination number (6 : 6); hcp; Zn⁺⁺ ion in all tetrahedral voids. (c) Coordination number (6 : 4); hcp; Zn⁺⁺ ion in all octahedral voids (d) Coordination number (4 : 4); ccp; Zn⁺⁺ ion in all tetrahedral voids.
@@chemistrydemystified9923 thanks but how kindly ma'am when you will upload the mcq of solid state kindly also involved these mcq a and explain them in your mcq videos☺
Picture a huge cube containing multiple of these smaller cubes, the corner atoms will be in 8 dimensions while the face centre atoms will only be in 2. This basically means a corner atom would be in 8 cubes, thus it's volume will be 1/8 per cube while the volume of a center atom will be divided by 2 cubes which means 1/2V per cube.
Assertion : In ZnO, the excess Zn^(2+) ions are present in interstitial sites. Reason : Metal excess crystals have either missing cation or anion in interstitial site. Kindly solve this question
Great explaination, thank you so much - from a Masters student in Germany
Ma’am you are genuinely the best!! Thank you so much for doing this, really really helped me out!!
Thank you cordially from a bsc first year engineering student.
Thank you so much for your efforts. I able to learn the concept completely seeing this video. 🙏
Thank you from Libya 🇱🇾
Great effort.
Thanks a lot for clearing doubts.
Thank you 😊 ma'am for your efforts ❤️

Thank you ma'am for clearing my all doubt💞.
It's just awesome thq a lot mam
This was great ma'am. Thankyou so much
Thank u... I can see your effort... Your explanation was daam good even good presentation... Impressive😍👍🤩... Thank u Mam...
Packing factor of hcp also needed.
Good technique of taught ❤
Good explanation ,, thanks alot
Thank u so much ma'am ❤🎉 i think every words comes by heart not by book ...just adorable ❤
You explained very easily ma'am
Best explanation for ever❤️
So blessed to get this video.. Your way of explanation are just amazing Mam.. Thank uu✨✨ keep going🎉
Best explanation,,thanks ma'am
Madam you are an excellent teacher.....kindly make videos on motifs
Thank you ma'am for your efforts
This was very helpful thank you
Welcome
This just powerful.
Thank you so much from a masters student. Copperbelt University, Zambia
Thank you very much madam best explanation i ever seen
🙏🙏🙏
Great effort 👍👍
Bahut bada doubt solve ho gaya thanks mam i am hindi medium student but sb samjh aa gaya 🤩
You are great🇿🇲🇿🇲🇿🇲🇿🇲🇿🇲🇿🇲🇿🇲🇿🇲🇿🇲🇿🇲. Please do more videos on Solid state science
🙏
Simple and great ❤
Thanks alot
follow you from Egypt 😊
🙏
Thank u so much medam..🙏🙏 your teaching is so beautiful and all things are easily understanding... love u mem🤗 plz make more videos mem..🙏
WELL EXPLAINED
Thank you that was so useful 💕

@@letdesignsomething7266 sure !
my emotion is above i thinking so much thanks
All doubts cleared ❤
Thx for your effort miss
From Egypt
Welcome 🙏
Fantastic mam 🙏😊👏👏
Great madam 🙏
THANK YOU SO MUCH...........
Thank you so much
Thank u so much mam😊❤
Thank you so much mam
opiest explanation mam!!!........😊😊🙏👌bestest explanation i ever seen...😍👌
Thanks again
Thank you ma'am
11:24 fan someone explain this part to me? i don't get it.. i thought its supposed to be a=4r/square root 2?? im so confused
حتى انا +2
اعتقد انها حفظ ؟!
Nice .
Thank you mam 💓
great
Tysm👍🏻
Good job
On 15:49 i feel there was a mistake. Is the AD=4r or 6r. I feel its 6r.
It is 4r. For two atoms at the corners only you have to count only 1r for each and for the atom in the centre. It is 2r. Hence 1r+1r+2r=4r
How the contribution of face centre cube is 1/2?
Picture a huge cube containing multiple of these smaller cubes, the corner atoms will be in 8 dimensions while the face centre atoms will only be in 2. This basically means a corner atom would be in 8 cubes, thus it's volume will be 1/8 per cube while the volume of a center atom will be divided by 2 cubes which means 1/2V per cube.
tq soo much mam
Thanks mam
Super madam
Madam very nice❤️🤩🤩🥰🥰😍😍😍.....how we will get no.of lattice points??tell me Madam please

14:18 pe 1×1+1 aayega
Tq ..
Mam diagram shows only 7 corner atom
Ma'am you have a mistake on number of (r) it's should be (3r)not (4r)
Isn't it supposed to be 6r ??
😮😮😮😮
Why can't you say the mathematical problems by line to line why are you like a bullet train mam??
Thank you ❤️
