22:38 Sir with due respect there is no node between 1s and 2s. Infact there is one node only in 2s and 1s and 2s electron densities convergentally overlap at nucleus. Regards Dr. Prabjot.
Aanad aa gaya sir ... Maza aa gaya kya hi bataun. ... Itane books padh liye lekin kahi pe bhi shielding and penetration ache se nahi diya hua h ..... But this time I know whole story about this . Thank you so much sir .
Sir... Ur words are very expensive. And ur way of teaching is....... I can't explain .. Lots of respect..... For you. And thank you so much sir.. Thank you...
It is a phenomenon of reduction of force of attraction between nucleus and valence shell Penetration and shielding both are same it means a screen which is reducing the amount of force acting by nucleus towards valence shell
No actually s and p electrons hv negative charge density so s electrons repel p electrons. According to Coulomb's law. Therefore p electrons goes outside.
One of the best teacher in this world... Best teaching skill,,, outstanding sir ... You are awsome,,,, it is not possible to compare you with any one ...
Respected Sir... i have a question ..... Hydrogen have 1 e- i.e hydrogen is monoelectronic specie if we provide enegry to 1s e- of hydrogen , the e- will promote which sub shell i.e 2s subshell or 2 p sub- shell ??? as both are degenerate plz sir rply.......
Sir....., Ur energy of teaching makes me so energetic...... Nd, i really njoyed this video...... Thanks for such an amazing video....sir..... Ur teaching video gives me positive vibes.....
Sir you said s orbital have symmetrical charge distribution and have high nuclear charge But sir s orbitals have high sheilding effect and have less zeff?
Thank uh very Very Very much sir I was so confused about my teaching platform for csir net but your single lecture gave me a clear direction now I can say uh guru ji in real means who can direct us properly for our destination I can't explain sir how uh helped me out by your lecture
Sir ager dono 2s Or 2p same distance pe the to jaise 2s ka penetration hua to 2p ka bhi penetration hona chahiye tha na... Bcoz both are same distance na... Wo kyo neuclous ki or attraction form bhi kr paya s subshell k barabr?
can a atom show penetration and sheiding effect when two electrons are present in 1s orbital as it is a polyelectronic species? Because atom has no 2nd shell(eg.Helium).which orbital penetrate towards inner orbital.
Sir s orbital mei agar 2 electron fill h i.e helium and p orbital fill nhi h aur according to quantum no if n = 1 l = 0 i.e only s orbital is possible then isme kaise penetration hoga Why are we assuming that s electron will excite into 2s orbital,may be it will not go then in that case should penetration occurs? We can also assume that we are exciting both the electrons in 2s orbitals then in that case what happens.
Sir, apne jo 3rd energy level mein degeneracy ka q. pucha h. Vahan pr (px, py, ) ka (pz) s kam hoga, to vo fir degenerate nhi hue H- ka ans. 2 hona chahiye na?????
Sir one doubt if 2s sheild nucleus than there is still 2p orbital coming from the center of nucleus as u have shown... Than how can 2s shield nucleus if 2p is coming from middle of nucleus.....
Shelding and panetration both will work when orbital have electrons right Now if penetration takes place due to one or two electron in 2s orbital and their is no electron in p orbital So 1. Did shiling will takes place in 2p orbital (which is empty) ? Or 2. shiling will not take place only penetration phenomena happen in 2s orbital ? bit confusing plez help me sir

Ved sir which clear all type of chemistry related doubt .
Outstanding teaching style
Thank you sir u r legend of chemistry

Bohot ichha thi sir aapse padhne ki, jo aapne puri kr di thanks sir,

Helo bro help me
Sir iit jam k liye kitne lectures tk dekhna hai ?? Is series ko?
Thanku so much sir my good wishes to them❣️❣️
Nmste sir....me chemistry ko zero se suru krke sikhna chahti hu to plz suggest me....muje kya krna chahiye....konsa course lena chahiye
Ekdum dhua...garda uda dia ved sir....chemical bonding ke ved ka gyan de dia sir apne
Isse best kuch nhi ho skta h sir 🙌
Thank you
Thnku so much sir😇I have no words, ur teaching style is unique.
Ha na bhai.
Thanks sir for helping chemistry students and teachers as well.
Sir please organometallic ka complete video daliye🙏🙏🙏❤️
Sir how p goes outside
When s comes inside during attraction then automatically distance between s and p increases.
No actually s and p electrons hv negative charge density so s electrons repel p electrons. According to Coulomb's law. Therefore p electrons goes outside.
@Sanjay Chem thanks a lot
Ved sir .....Aap ke baare me jitna suna tha us se bahut zyaada h aap .....sir aap ke concept koi hila nahi saakta .....thanks sir
Thanks for the kind words ! Stay connected
Amazing explanation 👍👍👍

In Hydride there is no electron in 2s , both are in 1s, then why penetration is working on 2s
Same doubt
Sir ne Bola tha we take excitation case there but I have same doubt I will check that on google
Same doubt here much confused

But sir s orbitals have high sheilding effect and have less zeff?

Thanks alot sir🌹
Sir In He atom there is no 2s electron so how will there be penetration and shielding? Please reply, thank you

Good evening Ved Sir.
Can you please upload videos for Main group Chemistry after Bonding??
The best vedios ever are here,,very very smoothly explained and i just love to have chemistry by ved sir❤️❤️

Best teacher of youtube
You are blessed with unusual talent of simplyfying comples things Truly respect sir I can compare you with our God mr Walter levin

Sir u are ausome . U are best
can a atom show penetration and sheiding effect when two electrons are present in 1s orbital as it is a polyelectronic species? Because atom has no 2nd shell(eg.Helium).which orbital penetrate towards inner orbital.
Best sir for inorganic chem.
Sir s orbital mei agar 2 electron fill h i.e helium and p orbital fill nhi h aur according to quantum no if n = 1 l = 0 i.e only s orbital is possible then isme kaise penetration hoga
Why are we assuming that s electron will excite into 2s orbital,may be it will not go then in that case should penetration occurs?
We can also assume that we are exciting both the electrons in 2s orbitals then in that case what happens.
Such a good way to explain everything. Thanks for this sir
Love you Sir from Kashmir
Sir pls clear my confusion
S & p orbital same shell me he...
To electron s me he ya p me kya pata kyo ki s & p are in same size
You are not only providing us better content but also getting alots of blessing from students ❤️❤️
Outstanding explanation...I have understood each and every word of you...👍👍👍
Thank you so much sir...you're energy leads better understanding of chemistry😇😇

It is very helpful for me your teaching method is awesome and thanks sir
You are one of the best teacher
Is it possible sheilding between two subshells which are residing inside to different(energetically) shells

Sir, apne jo 3rd energy level mein degeneracy ka q. pucha h.
Vahan pr (px, py, ) ka (pz) s kam hoga, to vo fir degenerate nhi hue

Please reply sir
Sir one doubt if 2s sheild nucleus than there is still 2p orbital coming from the center of nucleus as u have shown... Than how can 2s shield nucleus if 2p is coming from middle of nucleus.....
You read Amazing sir 😃😃 your voice is very exited . I really appreciate for your help .thanku sir😊😊😊
Sir to why 2s expansion will not occur...by 1s electronic repulsion...why its size will decrease??
Bahut hi badhiya laga sir
Sir kya iit jam ka Sare syllabus k lecture mil jayenge
Sir Kya same phenomenon surface tension m bhi lgta h Kya sir please explain
Loved the way of teaching
Bhut aage jayega chennal aapka
Sir,2s mein agr 2 electron or 2p mein nhi h koi electron..toh kya 2p orbital expand hogi? Shielding hogi?
Thanks you sir, bohot achha samajh mai aya
Is this the full portion for IIT JAM
U r a great teacher.
Very very thank you sir jee aap me bahut hee accha padhaya Hai
Really sir.u.r.soo.great🥰🥰🥰🥰
Shelding and panetration both will work when orbital have electrons right
Now if penetration takes place due to one or two electron in 2s orbital and their is no electron in p orbital
So
1. Did shiling will takes place in 2p orbital (which is empty) ?
Or 2. shiling will not take place only penetration phenomena happen in 2s orbital ?
bit confusing plez help me sir
@@VedPrepChemAcademy when?
29:36 Sir, but if there were no electrons in the beginning, how can we define electron clouds for the atom?
It's just fantastic lecture
Sir ap bahut hi deeply padate ho thank a lot sir
🙏🙏 Welcome! Stay Connected & keep learning 🙏 🙏
Thanks sir for easy explanation of shielding and penetration effect.
Your Welcome..stay connected keep sharing!!
Sir, so there is no penetration of 1S electron in a polyeletronic system. Am I correct?
