Dude you’re the best teacher so far.. giving quality in a less amount of time. Did 2-3 topics from your videos and your teaching style is just fabulous 🫶🏼
I was having a hard time understanding Bohr's atomic model from my text book, it was so boring and had so much unnecessary information. 5 minutes of this video taught me what my textbook couldn't. Thanks for the fun and informative video!
thankyou so much sir. u explain very well using graphics it's so much better than sitting and attending those boring lectures of 1-2 hrs. looking forward to biology and physics concepts for class 11.
Excellent explanation if concept in a short period of time. A small correction to a NAJAM Academy team to Correct the formula for K.E as 13.6 Z square/N square instead of 3.16 Z square/N square instead . Thank u
It's my final exam after 1 week.I didn't completed even a single chapter of my chemistry book.Now I am going through your video.Your videos are very heplful.

Sir thank you very much for explaining this concept i cant say how to express my feelings that how you explain once again thankyou thank you very very much sir
Along with the radius of an electron in hydrogen atom please do provide the energy of an electron in hydrogen atom. Derivation of radius and energy of an electron in hydrogen atom
The letters K, L, M, and N are used to denote the electron shells in an atom instead of A, B, C, D due to historical reasons. These letters were introduced by Charles G. Barkla, a British physicist, in the early 20th century when he was studying X-rays. Barkla discovered that X-rays emitted by atoms had distinct energy levels, which he referred to as different types of rays, initially labeled as A, B, etc. However, when he realized that these "A" rays didn't exist, he started with "K" to avoid confusion. Thus, the first energy level was called the K-shell, followed by L, M, and N for subsequent energy levels. This nomenclature has persisted in atomic physics and chemistry.❤
Sir why electron is taken from infinity?? When an electron is taken from infinity,then it is not potential energy.actually it is absolute potential energy.seconfly why potential energy decreases
I have no words to appreciate your method of teaching. I will just say that i am proud of that i have teacher like tho...
Love and respect 🙏 ❤️

When i multiply 0.53 to the 3²,the answer is 4.77 but najam writes 4.76 ,why???? Plzzzz guide me

6:04 according to Bohr baba was epic 😂😂😅
And coulomb baba 😂😂😂
What is epic😤

REALLY YOU ARE GREAT SIR🎉🎉
You don't know how greatful I am! May God bless you
Excellent explanation if concept in a short period of time. A small correction to a NAJAM Academy team to Correct the formula for K.E as 13.6 Z square/N square instead of 3.16 Z square/N square instead . Thank u
nothing is wrong he just used different units
Thank you very much for uploading frequently.
Sir i think the value of K.E is 13.6Z²/n² and total energy is -13.6Z²/n²
Ha bhai is liye to me pareshan ho rha tha,mujhe pata tha ishka solution comments me hoga,dout clear, thanks
You're right because z=2,the answer is13.6
Wow, u the best I have ever seen,
I will be an expert in my discussion group today
Sir, can you make a video on heisenbergs uncertainity principley..Your videos are amazing it helped me a lot. Lot of thanks..
It is already uploaded
Best lecture i have ever seen... Sir you are the best.. We want more video
Thank you so much
the most worth video I hve ever watched thank youuuu you deserve as million
This is sooo amazing ❤ Thankyou sir for this , you're explanation is very clear 👌🏻 😊
Thank-you thank-you thank-you so muchhh ....you saved a lot of time of mine.....☺️☺️
Tq so much for clear explanation 🙏🏻✨
I'm from Ethiopia teaching the mathod is out of this world amazing teacher I ever seen
Hi
It's my final exam after 1 week.I didn't completed even a single chapter of my chemistry book.Now I am going through your video.Your videos are very heplful.
Ab Kitna hi kr lega😂
10:28 the value of radius of L shell is 2.12
Your way of teaching is superb, simple and exciting. Keep it up
Your teaching method is ingenious💙💙

Masha Allah sir
Ap ka explaination bhut effective and Limited bi ha
Good Methodology
Amazing...respected sir...thanks for providing

The way that u choose for explaining is very creative and understanding you are saving our time thank you so much
Marvelous teaching 🔥
Your explanation is amazing sir I'm glad to visit ur channel now I'm one of ur subscriber i wish u hit 1M subscribers
U r my best teacher 💓 sir , really i never 👀 a sir like you 😊😊
Sir There is probability of finding 2s electrons in the 2s orbital near the nucleus. How can this be possible when there is 1s orbital in between ?

Sir actually the value of kinetic energy of electron is -13.6 z2/n2
Same bro😊
Appreciating you genius guy❤
You are so genus i have no idea keep it up from Ethiopian ❤
MASTERPIECE!!! Why didn't I find it before my half yearly exam!!! :(
Hi sir I like your channel .U R wonderful explainer 👏👏👏
Your teaching was just wow😊
thank you sooo much sir . It is very important and useful for us
Sir your teaching style is unique one.(easy+all concept clear).
Amazing!! Your videos are very understandable, whether it is physics, chemistry or biology.
Your way to explain things is very very helpful and easy ❤
Really GREAT 💯 No words to praise you
Great 💯 no words to praise 😊😊❤
You are a nice and genius teacher 💖💖💖💖💖💖💖
Shouldn't K.E. be 13.6 (Z/n)^2 eV??? Or I am wrong???
No bro you are right,13.6is real answer
You are right
@@prathimaha2812according to book value ,13.6 is correct
Right
THANKS FOR SUCH A GREAT EXPLANATION 😇💫🌸
SIR PLZ MAKE A VEDIO LECTURE ON TOPIC--> STATES OF MATTER✌😊
Doubt sir..
In velocity of electron how can we cancel n and h when both are in numerator sir 😥
Sir thank you very much for explaining this concept i cant say how to express my feelings that how you explain once again thankyou thank you very very much sir
Thank You So Much 🥰💟😘
Thank u soo much sir u made this concept so easy for us ❤
One heart🫀 for a good/excelent teacher from a honest student
you the man of teaching
Appreciable Work Done by The Najam Academy❤❤❤
You're saving lives
It was very detailed Is it for 11th grade cbse. Found things difficult.
Good teaching i appreciate you
This has really helped me thank you so much
I am gradually falling for physics..and chem...bec of u
Love you sir ❣️ your teaching style and art and your honesty towards your work is brilliant 🙏 keep growing 💗

Sir please make a video on atomic spectra in detail
Sir please upload the video on chemical bonding
10:47 it is 4.77 sir please check it😅
Kia ye lectures first year k lie b hai .?!!’
Thank you very much sir easy to understanding the bohr atomic model
What is Stoichiometry?
Calculation based on the balanced chemical equations are called stoichiometry.
Thanks sir
We waiting for us physics tutorials
Very relatable illustration in introduction

In calculation of radius hydrogen contains only one shell how you calculated to M, N shell?
Thank you so much 😊
in the r=0.53 2²/1 = 2.11A° isnt that 2.12A°? or i just understand it wrong
and the third 4.76A° should be 4.77A°??????? ahhhhhhh
U r right me too got same .. but I Clarified
The best one I got ❤ thanks a lottt🎉❤❤
It's really helpful ❤
Very good video thank you sir
Awesome explanation
i woll recommend this channel to all my friends 🙏🏻
greatt✨
Please do on line spectra of hydrogen ....
Love you sir, thanks you for teaching..
Can you teach in hindi language??? ❤️❤️
😂😂😂😂😂😂
wow bro
Sir start physics topics too especially mechanics
plz make lecture on types of fluid flows Bernoulli's principle
Sir you said that electron revolve in fix path or orbit then why you said that electron jum from one shell to another
Jump
Please can u explain me atomic structure
Super explanation i understood very well keep it up😊
So beautiful so eligent just looking like a wow
Sir 3hr class 23min 🤩🤩 21:11
You are so genioues
Sir please explain discovery of electron proton neutron
Bro if you will join any School or collage You can become director of the subject you will teach
Great 😍
