Packing fraction in HCP | Hexagonal close packing | packing efficiency of HCP in 2D | Solid State

In this video I discussed Packing fraction in HCP/ Hexagonal close packing /packing efficiency of HCP in 2D /solid state

[@sriramanbezhil4032]

Mam, I was a student very very weak in chemistry initially but with God's grace i accidentally got a good tutor like you. I would always pray for your good health mam...great hearted teachers like you are actually the backbone of our knowledge.

[@no3224]

Yes,brother

[@parameswaranpillai134]

The presentation of the teacher about one dimensional close packing and two, three dimensional close packing voids and calculation of packing fraction is explained effectively and efficiently in a normal speed using. models with nice voice without Committing any Mistake is laudable I. Thank you for clearing som of my doubts about A. ,B,C types packing.

[@OntologicalQuandry]

Thank you! This is a worthwhile video to reach a salient number with proof of it. I am not spoiling the result as the method is well worth the result. Thank you for such a clear video.

Hello madam..I am a great fan of yours! You give me so much of motivation through you videos Mada. actually I took a drop in 2017 for NEET but didnt give my best as a result I didnt qualify..I went to Apollo hospital few days back for my mother's treatment and by seeing those doctors I developed a burning desire of trying once again..So i decided to give a drop once again in 2018 for NEET but yesterday while reading some quora questions I came to know about NTA and saw some peoplw saying that NEET 2019 wont be same like earlier.NcErt questions wont be asked and many more.so madam I request you please do upload a video about this NTA and the changes that will be done in NEET 2019 please madam I request you ..I hope you would see this message I seriously hope you would clear my confusion..please help ...my decision is depending upon you now...please help
