This was the video which i needed in class 7th-8th. Especially if you are an ICSE board student and dont want to learn chemical formulas in early classes (7th/8th) even though the teachers tell you to learn them. This is the best video. At the same time, refer to the First Chapter in Viraf Dalals ICSE Chemistry Book for class 9th. You will find a valency table, just by heart it and watch this video 2 times and you are free to go and form almost all the simple compound formulas
One thing really crucial to say , I searched for millions of videos for chemistry as it's my weakest point , couldn't understand anywhere. I was confused watching so many concepts but your speed , teaching skills and mentorship is brilliant .... Thank you sir

Bhai CORRECTION : Na+ toh cation h toh vo toh lena Chahta h electrons , Cl- toh anion h vo dena chahta h . At 3:06 mins you told sodium has excess electrons while in reality it has deficiency of one electron
Unhone sahi hi kaha Hai kyunki sodium ke pass ek extra electron hai jise wo kisi aur element ko de kar khud balance ho jayega aur ek electron Dene se hi use last shell me aath electrons aa jayenge
Thank You So Much Sir. I had trouble with the chemical formulas, it was because I hadnt memorized this table but after watching this video all of the chemistry balancing equations became very easy
I have followed you for almost a year now. I used to fear chemistry when I was in 8th. But now that I am in 9th, mere grades mey bahut drastic change hua hai. Mai 45% se seedha 94% per aa gayi hoon all thanks to your explanation! Please keep making videos like this!❤

Sir you are an amazing teacher. You teaches us with all your strength and your energy during the whole class is amazing..... I hope everyone will gain more than 95% in their boards if they listen to you carefully and follow your footsteps 😃👍
Sir I have a doubt and I am really struggling with it right now as I am covering up my basic chemistry topics to rock and roll my basic is only I need to backup Doubt is: if formula of carbonate is CO3² ( the valency is -2) and hydrogen is H+ then how can we prove hydrogen carbonate is HCO3 in your given chart by Criss cross method , ( the valency of co3 is -2 and hydrogen +1 so if we do Criss cross method it should be H2CO3 . Waiting eagerly for your reply sir.
Great question! The answer lies in how we interpret hydrogen carbonate (HCO₃⁻) versus carbonic acid (H₂CO₃). Here's the breakdown: Hydrogen Carbonate (HCO₃⁻) Hydrogen carbonate, also called bicarbonate, is an anion (negatively charged ion) with the formula HCO₃⁻. To form hydrogen carbonate, we add one hydrogen ion (H⁺) to carbonate (CO₃²⁻). When H⁺ combines with CO₃²⁻, it balances out to give HCO₃⁻ (a 1- charge), rather than H₂CO₃. This is because we’re not adding enough hydrogen ions to fully neutralize the carbonate's charge. Carbonic Acid (H₂CO₃) H₂CO₃ is the neutral molecule formed when two H⁺ ions combine with CO₃²⁻ to fully balance the charge. If you were to apply the criss-cross method with H⁺ (1+) and CO₃²⁻ (2-), you would indeed get H₂CO₃ - carbonic acid. Key Difference: HCO₃⁻ (hydrogen carbonate) has a 1- charge because only one hydrogen ion is added to carbonate. H₂CO₃ (carbonic acid) is neutral because two hydrogen ions are added to balance out the carbonate's 2- charge. In summary: Hydrogen carbonate (HCO₃⁻) results from adding one H⁺ to CO₃²⁻. Carbonic acid (H₂CO₃) comes from adding two H⁺ ions to CO₃²⁻.
Bhaiya your explanation is awesome.I am a 10th class student.I had many doubts in science I tried to find many videos but all are big and somehow boring but then I found your videos I got interest in studying first I thought you only send motivation videos but when I saw your science classes Haye bahut achi thi itna interest se to aaj tk nhi padha tha but sir now you are not doing any live classes my ss is very weak not only my I know many students whose ss is weak I would like if you could provide ss live sessions and thanks for your hard work and for making study easy and interesting 🙏🙏☺️

Sir I have a doubt and I am really struggling with it right now as I am covering up my basic chemistry topics to rock and roll my basic is only I need to backup
Doubt is: if formula of carbonate is CO3² ( the valency is -2) and hydrogen is H+ then how can we prove hydrogen carbonate is HCO3 in your given chart by Criss cross method , ( the valency of co3 is -2 and hydrogen +1 so if we do Criss cross method it should be H2CO3 . Waiting eagerly for your reply sir.
Great question! The answer lies in how we interpret hydrogen carbonate (HCO₃⁻) versus carbonic acid (H₂CO₃).
Here's the breakdown:
Hydrogen Carbonate (HCO₃⁻)
Hydrogen carbonate, also called bicarbonate, is an anion (negatively charged ion) with the formula HCO₃⁻.
To form hydrogen carbonate, we add one hydrogen ion (H⁺) to carbonate (CO₃²⁻).
When H⁺ combines with CO₃²⁻, it balances out to give HCO₃⁻ (a 1- charge), rather than H₂CO₃. This is because we’re not adding enough hydrogen ions to fully neutralize the carbonate's charge.
Carbonic Acid (H₂CO₃)
H₂CO₃ is the neutral molecule formed when two H⁺ ions combine with CO₃²⁻ to fully balance the charge.
If you were to apply the criss-cross method with H⁺ (1+) and CO₃²⁻ (2-), you would indeed get H₂CO₃ - carbonic acid.
Key Difference:
HCO₃⁻ (hydrogen carbonate) has a 1- charge because only one hydrogen ion is added to carbonate.
H₂CO₃ (carbonic acid) is neutral because two hydrogen ions are added to balance out the carbonate's 2- charge.
In summary:
Hydrogen carbonate (HCO₃⁻) results from adding one H⁺ to CO₃²⁻.
Carbonic acid (H₂CO₃) comes from adding two H⁺ ions to CO₃²⁻.
