[@DenovoTutor]

Awesome video! 🔥🔥🔥You inspired me to start my own tutoring channel 😃

[@TheOrganicChemistryTutor]

Thanks

[@johndoe-nu7wi]

Really nice mate, I subbed to your channel and @The Organic Chemistry Tutor, hope y'all grow

[@node_mlg863]

@@johndoe-nu7wi this is 4 years ago lol, so old

[@abdoulazizdabo9064]

Literally 3mn that all it took for me to understand the concept, I watched the video on the app that I bought with the book over and over again, but it still was confusing. Thank you 😊.

[@stephlon6757]

You are so amazing. thank you !

[@MrGlobalMoO]

I swear that you are a great man

Sir what is the quantum no.of magnesium

[@nurulaqilah9064]

thank you soooooooooooo muchh

[@bhavanasavani1584]

Very very well done 😆😆

Idk wt to say ....keep going 10q😘😘

[@MithunraiOG]

Hey how to find quantum numbers using atomic number

[@user-bv5sq9dy7w]

How come we count pairs as two and not one? Just curious

[@-banmditt.wiiick._]

how is the first question different to the 5th one...same question different work out approach?

[@titilayoolukunle2456]

Please what is the difference between your questions of number 16 and question number 21.....the approaches are different...can you please explain?

[@sanjaynair7718]

In the 16th question,the l value is mentioned whereas in the 21st question the l value is not mentioned....That is Y the approaches are different.....

[@maheshtumkurmaheshkp3903]

superbbbb

[@anuradhanonis1873]

superb

[@bewarjawdat9898]

great

[@raghuram5493]

In 4th question - One electron is excited from 4S sublevel to 3D sublevel and that's fine.
But, another electron is still present in 4S sublevel. Why that electron is not exciting to the 3D sublevel?

[@snowtothezone3231]

because an orbital can not be empty

[@iswaterwet530]

Really got tricked on that Chromium question there! Nonetheless, thank you for this!

[@AM-qn9jn]

at 24:13 isnt it actually 6 because you forgot about the 3d subshell and went straight from 3p to 4s?

[@richtofen6287]

It's because according to the (n + l) energy rule, the 4s subshell has lesser energy (4 + 0) as compared to the 3d subshell (3 + 2) and therefore gets occupied before 3d.

[@Airmarox]

Why didn't you just add the top numbers I.e 4+2 on the sub levels

[@angel-ik2mc]

Shouldn't the answer for number 5 be 32?

[@jennylynpan9311]

Can anyone answer this
How many electrons are there for an element whose last electron has the following quantum number n=5, l=4, m=-2, s=-1/2?

[@anastasiaclaude6217]

One electron

[@anastasiaclaude6217]

farah shrouk there is L=4 which is the g sub level having 9 orbitals and a maximum of 18 electrons

[@its_florence6474]

Sir when do we include l=4? Like sometimes we use only till l=3 so......

[@mccauleybacalla2228]

i got 0, thank you
