@@NAJAMACADEMY sir please voiceover these lectures in hindi so we can understand it more better and deep haa English me likhne ki toh answer to hum waise bhe likh le ge jab concept clear ho ga
You deserves an Award. In fact you are genius. Have summarized what many people completed University without knowing In just few minutes. And it makes sooooo much sense and easy to Understand. Almighty ALLAH Bless You.
So nicely and precisely explained. Thanks a lot sir. I was always use to be confused in this basic concept but u made it all clear. I think this video must be seen by everyone before studying chemistry
I have questions that at 4:00 minute you have said that di atomic molecule can exist freely and and one of their can't exist freely but may be that's wrong that di atomic molecule can't exist freely? Please confirm that sir..
Thanks!Everyone should watch it!! Though the voiceover is a little weird but still it will clear your fear of chemistry, as now you will know the meanings of these words whenever you see them!°
4:08 What do we mean by they can exist freely in nature? Like how they cannot be free in nature or what is the form of it being not free in nature Thank you for your explanation ❤️
Sir , Waha apne homoatomic combination ke sirf do hi part likhe h - monoatomic and diatomic, what about tri , tetra and poly atomic . Means for example S8 , O3 , P4 ye kisme aayege sir . Please reply
i have several doubts, Why are we not calling the monatomic molecules as compound but element? Why aren't we calling heteroatomic molecules group as element ? Does the word element only applies to the Monoatomic molecules groups alone? If the same atomic molecules form elements , how is there heteroatomic molecules exist? When mono atomic molecules combine together to form element would that be in any state (solid, gas,liquid)? For example that you stated, Ne Ne (neon) molecules of gas becomes element does that stay in gas form? Why metals like FE (iron) do not form molecules? what preventing them from forming it?
when atoms of same type join together then they are called as elements and when atoms of different types combine then they form compounds...btw the the questions you are asking are kind of basic i think you should have read the book first and listened to your teachers
I can never understand these thing before. But when i watch this video, i can easily understand all these thing in like what 10 minutes. Thank you so much🙏🏻
Ok, what about ionic compounds such as NaCl? 1. Are they also molecules as they are composed of hetero-atoms. 2. Why Are such compounds called formala units rather than molecule?
Sir, as you mentioned at the start that molecules are grouped together to form element... And, you said that metals don't form molecules. How?? Can anybody explain... Please sir..
Metals are solid except Mercury. All metals exist in crystalline state like crystals of salt. Secondly, they have 3 dimensional structures like cubic, rhombic, etc. So, metals don't form molecules like H2, O2, etc. I hope it will help you. 👍👍👍👋💕
