Ur technique of making we students teach is unique....n makes an average understand easily...hope if u could finish important topics of 11 and 12th....in a short n efficient way....:-D
Sir U help us to understand hard concepts very eAsily ...than U ...plz sir make video on "how to identify solid, liquid, gas.meyal and non metal....plz sir
According to mcqs point of view their will be an option(Try to solve all the four and then find out which one will be right if answer is -2 in any then it will be normal oxide if answer is -1 in any then peroxide and if answer is -1/2 in any of 4 options then it will be superoxide.In short question it may not be asked.
Let me explain it for you... Just remember these famous metals: H, Na, K, Mg, Ca, Fe, Zn, etc... These are the famous non-metals: F, Cl, Br, O, N, C, etc... You can identify metals and non-metals in many substances if you remember them. For example, NaCl . (Na is metal and Cl is non-metal) CO2 . ( C is non-metal and O is also non-metal) MgBr2 . ( Mg is metal and Br is non-metal) Note it down this trick. It will help you a lot. Thanks!!! 🙌🙌❤❤
As u said an oxides of element forming multiple oxides e.g so,so2,so3 ,have oxidation number -2 then what about the oxidation number of oxides of carbon?
Bro it's just a compound not binary compound it contains more then two elements so the oxidation number will be -2. And about method it is applicable to binary compounds of oxygen.
Sir what u do at the last of this question? I could not understand this🤔. In peroxide and superoxide at the last u write that 2(1)+20=0... Second step..2+20=0 ...at the end I want to write 22=0 ....But u wrote that .0=_2/2...........But I couldn't understand this confusion....
Group 1 elements have oxidation state +1(except hydrogen because it forms +1 with non metals and -1 with metals) Group 2 elements have oxidation state of +2 Group 3 elements have oxidation state of +3 Group 4 elements have oxidation state of +4 Group 5 (varies) Group 6 (varies) Group 7(varies) Group 8 elements have oxidation state of 0(mostly)
Sir please make the video for classification of oxides based on their chemical behaviour sir and thank you very much sir for your well explaining videos🙂📙📙📖📖
Bro it is just a compound it has more then 2 elements so oxidation state of oxygen will be -2. In binary compounds, sir's method is applicable. When there are two elements in that one should be oxygen.so that oxides could be form.
Such a good difficulty is clear today in ur lecture thank u sir 🖤🥀

🙌❤❤
Please try....coz all ur tutorials gives me relief....for understanding topics....good luck brother... U have got a unique talent.
Sir tricks are superrr 👏👏👏. they are very helpful for us always and understand every concept easily.
💯💯💯💯💯💯💯💯💯💯💯
Thankyou sir
😀😀😀
I wanted to identify which is a peroxide to be able to know the oxidation no. of oxygen. In this video it's exactly the other way around 😭
Tq so much bro. You are the ray of sunshine
That's really very easy trik thank you 😊
Love love love to najam academy❤❤❤❤❤❤❤❤❤❤
❤Thank u so much
You are the most genius teacher in the world 😊
Who is with me ?
not me lil bro
Thank you sir for explaining it very clearly
Sir I knew this trick🖐️🖐️👍👍
1 atom of oxygen sir😊 1:02
❤😊
1st view pe hi subscribe krne pr majboor kiya😍🥰
Please! Sir continue the lectures!
I watch your every lecture!
It is very helpful for me!
Please! Make viseo on FSc Physics+chemistry+Bio subject!
I am trying my best...
Working 13 hours a day.
🙌❤❤❤
indian voice come in clutch
He clutched way more than a normal Indian 💀
Love from tamilnadu
Thanks sir such a surprise method
thank you, sir ... ur video helped me a lot
Sir U help us to understand hard concepts very eAsily ...than U ...plz sir make video on "how to identify solid, liquid, gas.meyal and non metal....plz sir
1:02 that’s oxygen not hydrogen
thanku sir aap be bhut acchey sey smjhaya
Sir but if we r asked lithium konsa oxide banata h to uspe ye trick kam nhi kr skti na ??
According to mcqs point of view their will be an option(Try to solve all the four and then find out which one will be right if answer is -2 in any then it will be normal oxide if answer is -1 in any then peroxide and if answer is -1/2 in any of 4 options then it will be superoxide.In short question it may not be asked.
Sir please make a video how to identify Matal and nonmatal in compound or molecules .
I will try my best!
🙌❤❤❤
@@NAJAMACADEMY sir please make a video Tomorrow plz sir
Let me explain it for you...
Just remember these famous metals:
H, Na, K, Mg, Ca, Fe, Zn, etc...
These are the famous non-metals:
F, Cl, Br, O, N, C, etc...
You can identify metals and non-metals in many substances if you remember them.
For example,
NaCl . (Na is metal and Cl is non-metal)
CO2 . ( C is non-metal and O is also non-metal)
MgBr2 . ( Mg is metal and Br is non-metal)
Note it down this trick.
It will help you a lot.
Thanks!!!
🙌🙌❤❤
@@NAJAMACADEMY Thankyou sir 🌺🌺
Did you learn it?
Or I should explain it further.
😊
Thanku sir this video is very great full
Sir means sulfur can only form oxides and not peroxide superoxide
It depends in different cases.
But mostly, they form oxides...
🙌❤
@@NAJAMACADEMY ok sir
if any compond oxigen==other no then sir????ie 1/2 or 3/2..
then what called????❓❓❓❓❓
Thank you so much sir 🙏🙃
As u said an oxides of element forming multiple oxides e.g so,so2,so3 ,have oxidation number -2 then what about the oxidation number of oxides of carbon?
Suboxide is not discussed??
oxidation number, the total number of electrons that an atom either gains or loses in order to form a chemical bond with another atom.
Wow sir too good 👍😊
Thanks sirrr 🥰🥰🥰🥰🥰❤️❤️❤️❤️❤️❤️❤️❤️
Welcome!!
🙌🙌❤
Very explanatory sir, thank you. Jussojuan
Excellent lecture
Sir🌟 we want vedio on isomerism please sir
Coming soon.
🙌🙌
sir, it's a bit lengthy method for solving MCQs can U tell me some easy and quick tricks for MCQs
How can determine oxide if the element shows multiple oxidation states?
You are so lit 😊 and did you make a video about the trick of type of oxide ?
Sir can you upload a video on '' how oxides formed ?''
please sir 🥺🥺🥺
We will try
@@NAJAMACADEMY Thankyou sir😀😀😀
CS is 2 nd grup only na sir...so we put 2 for CS is correct or not?
Cs is in 1A 1st group
Cs belong to group 1 and its o.s is =+1 which is always fixed, putting2 will be totally wrong.
Is this applicable to H2SO5 ??
Bro it's just a compound not binary compound it contains more then two elements so the oxidation number will be -2.
And about method it is applicable to binary compounds of oxygen.
Sir aap hydrocarbon chapter ki reaction Ko Yad karne ki tric bataiye🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻
Thank you so much dir
Sir then how to find the oxidation state of given atom
Sir can you explain why NO2 is oxide?
NO2 is Nitrogen Dioxide
Thank you so much sir
Kamal ka gyan dia 🙂 but mereko peroxide sa oxide likhna tha 🤡
Sir what u do at the last of this question? I could not understand this🤔. In peroxide and superoxide at the last u write that 2(1)+20=0... Second step..2+20=0 ...at the end I want to write 22=0 ....But u wrote that .0=_2/2...........But I couldn't understand this confusion....
Plzzz tell me It in your next video....
that 2O means 2×O(oxygen)
That's not 20 bro that's 2(oxygen symbols O 😅😅😅 looks same like zero 0)
Try again.....
Thank you🥰
thank youuu so much
Sir soft hard acid base with application plzzz sir
Thank you so much
Thank you sir
What about CO3?
Isomers. We need it .

Carbon group 4 ka kaise? 3:51
It is the element of group 4
Thanks sir ji
What is about group 5,6,7
Thanks Sir
Thank you

How to form the equation to get Na2O2 pls anybody can say??
See class 9 atoms and molecules chapter ncert
Effective
Great
how can we now their group
Generally ...
Group 1 Li , Na , k ,Rb,Cs,Fr __ os-+1always
Group 2. Be,mg, ca, Sr, Ba , Ra ___is +2always
Group 3. B, Al, Ga , In , Tl __os -3to +3
Group 1 elements have oxidation state +1(except hydrogen because it forms +1 with non metals and -1 with metals)
Group 2 elements have oxidation state of +2
Group 3 elements have oxidation state of +3
Group 4 elements have oxidation state of +4
Group 5 (varies)
Group 6 (varies)
Group 7(varies)
Group 8 elements have oxidation state of 0(mostly)
Sir please make the video for classification of oxides based on their chemical behaviour sir and thank you very much sir for your well explaining videos🙂📙📙📖📖
🤔 OOM PHO NICE
Use x instead of 0 in equation
Bro we are finding Oxygen not the X

Sir how can we find out that this compound is H²SO⁴
The given compound is peroxide or superoxide. As there is presence of SO⁵ in the compound
Bro it is just a compound it has more then 2 elements so oxidation state of oxygen will be -2.
In binary compounds, sir's method is applicable.
When there are two elements in that one should be oxygen.so that oxides could be form.
What a brilliant and amazing trick just keep it up sir🫶
Thanku so much sir🙏🙏🙏
