Sir thnk uh so much...jo apne NCert ke sare questions solve kiye....aur hame smjh bhi ayaa...sir aap aise hi vedio upload kiya kijiye🙏🙏

[srushti]

Thank you so much sir for this wonderful explanation 🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏👍👍👍👍

[durgeshkumarpathak]

I am Mritunjay, aapka videos mast hai sir, please aise hi video banate rahiye

[playwinpublicschool]

Uu must also gives notes on chemical bonding your teaching style is gudd

[rashikatamboli]

very good explanation . i love your way of teaching

[swikritichaudhary]

But sir, indium mein bhi toh d10 and s2 electron hain just like that in gallium then why
indium shows less effective nuclear charge than gallium. Indium mein toh nuclear charge gallium se aur badh kar, ionisation enthalpy aur bhi zyada ho jani chahiye thi.

[gunu]

Very good video.. I understood it. Yohooo

[nikhilkadiyan]

Just one doubt.
In Al and Ga, the outermost electron of Ga is ALSO shielded by d orbital in ADDITION to s and p orbital. So even if d prlvides low shiled it should add to the shielding of s and p orbital.
But you said that it will decrease the total shielding effect. That blew my mind.

This was reason I searched for this question in the first place. Please help me.

[pranavpratapsingh]

Nice explanation for every problems👌👌👌👌👌

[beauityofnature]

Paper sei pehele dekhnei ki aadat pad gyi hai😂

[yogeswarpandit]

Sir what is the meaning of the penultimate and pre-penultimate shell?

[HOORRRRRRRR]

Sorry sir but it's the only answer which I m unable 2 understand 👀😵😵😵

[Singh__anonymous]

Due to Lamrhenoid contraction..
Sir, I'm a NEET dropper student, your videos r really helpful🌼

[akanshajain]

I.E increase down the group due to shielding effect but aap keh rahe ho ki kam ho jaati h

[SUBZERO-nsps]

Not a satisfactory explanation please improve
