Doubt for 1st question: Sir, with due respect, Jo aapne answer Diya usme to answer ye bata rha hai ki kitni lines balmer series me fall karengi but mene padha tha ki balmer series me saari line visible region me nhi hoti sirf first four line hi visible region me aati hein. To lines in visible region to kabhi 4 ko extend karni hi nhi chahiye but acc. To your explanation, lets say n=12 and then balmer series me to 12 = 6 lines hongi but visible region to abhi bhi 4 hi honi chahiye na. Kyuki balmer region me sirf starting ki 4 lines hi visible region me hoti hein. Bas agar n≤6 hua tabhi vo formula valid hona chahiye kyuki agar aage ke shell ke liye vo balmer series ki total lines batayega na ki visible region ki I think ki vo formula number of line in a series ke liye hein but visible range ke liye tab Tak valid hai jab tak n≤6 na ho Agar n>6 hua to vo number of line in a series ke liye to sahi hoga but visible region me uske baat hmesha 4 line hi aayiengi Sorry if I said something something bad Please correct me if I am wrong❤️
Sir physical chemistry calculations are vast and almost undoable without calculator. pls show us the way to solve them down completely without using calculator even once. practice isn't bring that skill, pls help
Mere se bhi ho gye in less than 5 sec as 1) qs are easy and 2) concepts are clear. Acc to me this would be beneficial for school and mains only. BTW logic for all Trick 1 : we are analysing transition of n_higher (from where we start) to n_lower (given final destination, here visible => balmer => n_lower = 2). if we visualize the final transition, each's n_higher decreases by 1 every time (here 6->2,5->2,...,3->2) Trick 2 : Sir se badia main kya hi exolain karun iss wale ko (my input would be ki if we remember that energy is inderictly proportional to n^2, then its logical, jitna niche transition, utna bada energy gap) Trick 3 : My method is little different. I count number of times the graph touches the x-axis, so it gives me number of radial nodes, then i have remembered the nodes formula
i had a doubt reagading orbitals , will someone care to explain , so for 2s its meant to represnt the probability density for the second shell right , so why then in its visualization 1s is also included , and then its radial node becomes 1 , i mean if its like suppose aluminium for example wont that nodal region also have probability of finding e- because of all the different orientations of p's , someone pls help
Bonus point for second question: Red light emitted means visible spectrum, i.e. Balmer series, and only one of the lines was reaching n = 2 EDIT: I was mistaken, this is not correct, pls read comments to understand
While defining no. of unique/visible spectral lines we always rend to forget that sample is given or atom is given... That's the click of the question 🤍🪂
Dear Mohit Ryan/Arvind Kalia/Tharun Sir , can you please put the English subtitles. I had commented the same in one of your the underperformer IIT JEE Aspirant videos sir. Please sir 🙏🙏🙏🥺.
Sir graphical Schrodinger mein hum radial node dekh kr bhi toh kr skte hai jaise is question mein graph x axis pe ek baar touch kr rha hai matlab 1 radial node aur 2s ka (n-l-1) se 1 radial node hota hai mtlab ye match ho jayega
Literally dost, these qns gave me confidence I'm happy that i was able to keep up my pace with u, & also did learn another approach to the same qns LY3M ❤❤ I'm loving this series 😁
Sir iam in class 11th jee asiprant But sir aapne jo starting tricks batai main pehle se hi aise hi questions karta hoon but phir bhi atomic structure ke 50 - 60 % questions hi solve ho paate hai
#Trick 1:-[First ques]
n- given in the ques.
For balmer series:- n-2.
For any series we can use this trick n - ni(lower value of b acc to respective series).
#Trick 2.[2nd ques].
Red has the highest wavelength, by seeing the diagram only we can say tht line 3 to 2 having the lowest energy means highest wavelength.
#Trick3 [3rd ques]
Check num of peak = n- l.
In the figure we can see two peaks and by formula n-l we can say 2s is hving two peaks.
Hence b opt is the ans.
Thank you so much dost ❤
Love uh infinity moles❤️🔥

Thanks a lot. These videos really do help. Looking forward for more of these kind of videos
When did Haris Rauf Started Teaching Chemistry 🤯
After 18.5 in Melbourne 😂
😂😂
Sir at the same time you uploaded the video I was revising atomic structure chapter and was in need for such tricke
1 que mai agar infrared region diya toh kya karoge guruji ?
No. Of spectral line =(n2 - n1) (n2 - n1 + 1)/2
Sir same for mole concept
sure dost ❤
@@BeastChemistSir jitne chapters ke aese video la sakte la doo
1 more trick for ques 3rd is that counts only the roots of graph which is equal to radial nodes
yesss i did same
Thanks Alot Sir
Please bring more tips and short type content very helpful ❤❤
Sir are these lectures enough for jee
Arvind sir , its a request that please bring short cut trick videos of every chapter for jee 2024 aspirants🙏🏻
i had a doubt reagading orbitals , will someone care to explain , so for 2s its meant to represnt the probability density for the second shell right , so why then in its visualization 1s is also included , and then its radial node becomes 1 , i mean if its like suppose aluminium for example wont that nodal region also have probability of finding e- because of all the different orientations of p's , someone pls help
Sir pls give some shortcut trick for phsi questions
Amazing sir just amazing 👏
Thank u soo much 🙏🙂
Bonus point for second question: Red light emitted means visible spectrum, i.e. Balmer series, and only one of the lines was reaching n = 2
EDIT: I was mistaken, this is not correct, pls read comments to understand
Aap fans gaye dost.its a hypothetical atom.we cant apply that approach because all of the lines are visible.
LY3M❤
Ohh understood sir, thank you 🙏
R G B V i learnt that because it is in NCERT
Bahi usme Hypothetical atom tha, ye visible spectrum wala is only true for Hydrogen atom
Sir last question m apko kisa pata chala kie 2S hie hoga wo 2P v tho ho sakta h na
Nikhil sir had taught us the first trick❤ Arjuna jee 2025 pw attendance here
👇
Nikhil sir toh Arjuna neet main padate hain?!!!
Sir please make short trick videos for other chapter also 🙏🙏
While defining no. of unique/visible spectral lines we always rend to forget that sample is given or atom is given... That's the click of the question 🤍🪂
Sir please use English so that we(persons who don't know Hindi) can also got benefited
Sir same with mole concept
Dear Mohit Ryan/Arvind Kalia/Tharun Sir , can you please put the English subtitles. I had commented the same in one of your the underperformer IIT JEE Aspirant videos sir. Please sir 🙏🙏🙏🥺.
Dost i get confused in molality ,normality , molarity, please do something
Ab ye to formula based h ispe koi kuch thori kr skta h
sir we want more short and sweet videos like this
Shouldn't we include the reading time in solving art of 5 sec also😅
very impressive

@aryan4679Mohit sir.
Sr 2s wala smajh nhi aaya 2p kyu nhi ho skta
😮❤❤ need more videos like this ⚡
Sir please upload such kind of video for solutions, equilibrium and mole concept. Thank you.
Sir, please make a video on logarithm and modulus.
Could you please make such shortcut video for physics too pls?
Thanks dost
Great 🙏
Thx dost I am going to give a regular test today and this chapter is coming
this content are really help us
Wow nice trick ❤
isocyanic acid is a electron widrawing group how pls tell me
Sir iam in class 11th jee asiprant But sir aapne jo starting tricks batai main pehle se hi aise hi questions karta hoon but phir bhi atomic structure ke 50 - 60 % questions hi solve ho paate hai
positivity dost❤ wo bhi ho jayengey Bohr's Model per bhi bama dengey calculative Questions ke liye❤❤
Good start
Pw se ho na ?
Haan
Yes
Sir jitne chapters ke aese video la sakte la doo
sir jee 2024 ke liye peter sykes se mechanism padhlu? i have faith ki i can do !
Thank you so much dost❤❤
Plz give same trick for mole concept questions
Thank you so much sirji
For 3rd question
Formula is n-l-1
For 2s
N=2 l=0
2-0-1= 1
The graph also touches the origin only once
Hence 2s is ans
❤❤❤dost and bhai🎉🎉
Thank you sooooooooo much sir yahi question mere shift me phasa tha maine 5s ke andar solve kar diya ❤❤❤❤❤❤❤
Nikhil sir students also know this trick
You can calculate no. Of peaks directly by l +1 (where l is azimuthal quantum number).
Sir can you make a video in English
Pls take class on English bro😮😮😮 we also like to learn😊😊😊😊😊❤❤❤❤❤
Sir make this for vectors😢
ESI video exam ki ek raat pehle hi kyu milti hai😢
Thanks Sor
Viewers may also visit 'Learner's Console ' for this chapter too 🙏
Please for mole concept
Vedantu and unaccademy have some connection🤔
Sad reality of jee aspirants is strategy videos get more views then compared to videoz like this
Sir pls make also revision video for chemistry hole chap in one video
Amazing ❤🎉🎉Ly3M dost❤❤
bhai 1st ka answer to 6 hai....

Meanwhile ye trick toh khud hi invent jarke ysse kar rahe the pata chala ki ye toh pehle se hi exist jarti hain...
Tu pehle type krna sikhle bhai
Ye trick hai muje to lagta tha yahi method hai 🥴
second ques mie toh kuch zarurat bhi nhi thi trick ki balmer series ki ek hi line thi aur pucha tha red kon emit kregi aka visible region
