dude just imagine the hard work he puts in every single video writing and erasing , stopping and opening camera again and over again and then again restart shooting ufff literally impressed

[@zuruzuruwewe]

He seems like such a genuine and kind guy. I love how he is so articulate with his explanations. He ACTUALLY explains the answer instead of just making statements.

[@feather-l1g]

guys let me tell you this....if you have not studied anything (absolutely nothing) then you must memorize all the questions showed here...i guarantee you wil see most of the questions in your preboards/boards are asked directly from here. and if you have covered your syllabus then you must watch these videos..for revision and i again guuarantee you will encouter exactly same questions. i experienced this yesterday ( my chem preboard was there) and almost all the questons were just picked from here it seemed.

Atomic configuration of cerium is wrong in question no. 4 as it is 4f^2 6s^2, thus looses 4 electrons and forms Ce^4

[@sandhyayadav4837]

No.its right 👍

[@Bhavya_Rathore_99]

Dear u have some misunderstanding Sir's Electronic configuration is correct Ce- [Xe] 4f^1 5d^1 6s^2 Ce^4-[Xe]

[@abhinavkohli18]

31:08 sir completely filled d orbital hai. To fir bond weak kaise

[@SonaliPehal]

Because enthalpy of atomization decrease ho jati hai kyunki there r no unpaired electrons in d subshell And zinc apne aap se bond nhi Bana Pata because enthalpy of atomization kmm hoti hai so this is why it is called soft metal

[@SonaliPehal]

And also metallic bonding kmm ho jati hai because zinc cannot form bond with itself
