What a fantastic way of teaching. u have the ability to convert an average student to Genius. U take care of tbe students n the God will take care of you. MY BEST WISHES TO YOU.
Good evening sir ! Can you please upload video on Electropositivity & electronegativity Of elements! And the whole chart!!! Like coming from up it increases or decreases..... please sir !!!
I have not attended the live class but after seeing this questions I came to know more about period table by answering the questions for myself.Thank you sir!
1. b -mendeleev 2. d-4 3. b-56 4. a-fluorine 5. d-atomic mass 6. d-krypton(atomic size increase down the group) 7. C-increases and then decreases 8. C-Same place as atomic no is same for isotopes 9. B-decreses 10. A-2 11. Atomic Number 12. 3rd period,Group 13 13. 28 14. Non Metal Because It's E.C is 2,8,7 so it has to gain 1electron. Elements with 5,6or 7electron in their outermost shell are non metals.
The nature of the element =>Z=17 . E.C will be 2 8 7. The element should gain 1 electron to get stable state. Hence,it is a non metal (halogen). Coz all the non metals has tendency to gain electron.. Sir became a fan of YOU nd the way of explanation is too good😃😃
ATQ atomic number of given element is 17 so, electronic confriguration is 2,8,7 From this it is clear that the element can easily gain electron, therefore it is non metal (B) Your teaching is so amazing 💕 Please think about MENTI
GIVEN ATOMIC NUMBER IS : 17 SO,IT'S ELECTRONIC CONFIGURATION: 2,8,7. IT SHOULD TAKE ONE ELECTRON TO COMPLETE IT'S OCTADE , AS TAKING ONE ELECTRON IS EASIER THAN GIVING 7 ELECTRON. SO IT WILL GAIN ONE ELECTRON AND NON - METALS HAVE TENDENCY TO GAIN ELECTRON. .: SO IT IS NON - METAL ELEMENT NAME -"CHLORINE". AND THANK YOU SIR 🙂
Sir, the way of your teaching is amazing and please teach class 10 cbse maths, chapter 10 - circles in your youtube channel. so, it is very helpful for class 10 cbse students. Please sir it is my kind request, please reply me and teach soon sir. Thank you!
Sir I am not from cbse or icc board but I like ur videos u teach us such a way that we learn thanks for your explanation sir please keep doing like this
It is non metal Electronic configuration = 2,8,7 Gains 1 electron Thank you sir.. I loved it . Manocha academy is the best because he teaches In a fun way and shows experiments which makes it easier to understand. You also make the class interesting. Love Manocha academy ❤️
26.57 sir why is the electronic configuration of Krypton written as 2,8,18,8 ? I mean a shell only has capacity to hold 8 electrons even if the third can hold 18 electron according to 2n² rule. If you explain it...
Non metal Electronic configuration=1s2 2s2 2p6 3s2 3p5 As the last electron is in p orbital it belongs to p block and p block elements are non metals and Noble gases as 17 element is not a noble gas it is a non metal The element is chlorine
Hello Sir, I am a little confused about 1 thing; one your website you have courses for classes 8, 9 and 10. What is this equivalent to in the UK? Is this year 10 and 11, or is this a- level? Thank you for your great teaching, you have a talent for teaching others.
Homework ans is b) non metal . Thank u sir for all of u r videos . As we get these videos when we pay membership but u r giving these at free of cost .
In the video about concave and convex mirror I said that I will recommend this channel to them and I have. They are very happy with your classes. I and Neha scored the highest in our class for the class test on the chapter we hated the most. Thank you sir. Your classes helped me a lot during this time. I can't find words to say how thankful I am.❤️🙏
Sir, to me you are the Father of Chemistry. Before this, I thought that chemistry is only about memorising a bunch of formulas. But you became the Mendeleev and totally changed the concept. Thanks a lot, sir.
Thank u sir u r awsm🥺💝This chptr ws really hard 4 me .... i was watching many videos to undrstnd and Finally I ended up seeing ur videos ........At last I attended ur quiz now I really understand this chapter ....Now Iam feeling like I hv mstrs in this...OMG😂😂Iam prprng for my test ....I hope I will be able to score good marks aftr seeing this.....Tnq so much sir luv u lootss🥰🥰💝💝
Sir, your videos are amazing. However, I have a question. How did you study a chapter in a science textbook. Did you memorise or did you highlight the most important information and understand them instead of memorise.
Sir I have doubt n it is that can I explain covalent bonds n how they are formed I meant to say that those kind of figures which is in shape of hexagon something like that . Btw I had learnt 110 elements in class 6 only n now I m in class 8 and learnt all. Thanking you
The answer is non metal because the electronic configuration by 2n² method is 2,8,7(chlorine) and it will lose 1 electron to become totally stable in nature and by spdf method it will be [Ne] 3s² 3p⁵.😎 Sorry sir bcoz I have studied spdf method also O_o
superb sir! i am your fan and i also recommend my friends/classmates to see your video and subscribe and they to love it but sir actually i am in class 6 so i cant understand everything so pls can you make a video for class 6 toooo pls sir. thank you
Ans): non metal sir (1)Valence is greater than or equla to 5 then it is non metal (2)Valence is less then or equla to 3 then it is metal (3) valence is equal to 4 then it is metalloid 😀😀😀
There is no simple way since accurate mass is the sum of masses of protons, neutrons and electrons. Also you have to into account isotope ratio (e.g. Cl) Approximate atomic mass = mass no (amu).
What a fantastic way of teaching. u have the ability to convert an average student to Genius. U take care of tbe students n the God will take care of you. MY BEST WISHES TO YOU.

Thanks for your feedback. We'll look into the Menti Quiz format too!
Rely enjoyed this session! You make chemistry so easy.
Super session it is very useful for children ☺️
You make things really interesting and quite easy to understand.Thank you very very much.

Pls sir tell me what's timing is " live quiz classes" please......

Sir this helped me a lot
Thank u very much
Glad to hear that :)
The atomic mass of 28u.
As atomic mass of B=A+B/2

There is no simple way since accurate mass is the sum of masses of protons, neutrons and electrons. Also you have to into account isotope ratio (e.g. Cl)
