Thank you so much sir for your explanation. Actually I really enjoy the class and you are the only best teacher ever I met... No words to describe you sir. Thanks a lot 🙏🙏
Because electrons, protons, neutrons are the parts of an atom. They are not individual particles. These are not particles but only a part. Remember an atom can't be divided.👍👍
Atoms aren't the smallest particle. They're the smallest particle that take place in chemical reactions. Which also means that they are the smallest "whole particles". As neutron, proton and electrons can't exist freely, they are parts of an atom.
Hi sir ! I am from Kolkata and I am new to the channel. Sir your teaching is wonderful. But, please tell me about the differences between ions and radicles.
hi..i think I can help ions are electrically charged atoms and they are formed when an atom losses or gains an electron or electrons and radical is an ion with two or more different atoms acting as a charged unit hope this helps😄
Sir,u r great,your explanation is superb!......evn our scul teachr dosn't teach/explain like u,I really like your video n explantion too.Lve from Manipur(North-East)
I like chemistry, i think i have learned a lot, but i somehow still dont understand the basics. For example, nitrogen has valency -3, it can make three connections, so molecule NH3 makes perfect sense. But why is pure nitrogen N2 instead of N4? I can even visualise such square molecule with N atom in each corner, so why is that not the case?
Really Thank you so much sir...you helped me a lot and cleared all my doubts....I wanna share ur great teaching channel to my frnds...Thank u so much sir...
I have enjoyed a lot and I have also improved my chemistry after seeing this video. my teacher is appreciated me .. So I'm thankful to you sir for giving me a great class ..

I've a doubt - Why is atom the smallest particle of matter even though there are Electrons, Protons and Neutrons??
Because electrons, protons, neutrons are the parts of an atom. They are not individual particles. These are not particles but only a part. Remember an atom can't be divided.👍👍
RESTUDY THE CHP PROPERLY BROO XD
Atoms aren't the smallest particle. They're the smallest particle that take place in chemical reactions. Which also means that they are the smallest "whole particles". As neutron, proton and electrons can't exist freely, they are parts of an atom.

By seeing atomicity we can know the valency
Atomicity and valency numbers are not connected. Better to learn them separately.
