maam in the video of d block we discussed that due to electrons in d-orbital get excited they get excited state but as they are not stable in that they get back and due to tht energy release we see colours but here why @22:08 La and Lu are not showing colour as they also have d-orbital?

Wonderful lecture However there is one editing mistake at 32:12 . The oval shape incudes a lanthanide and actinide in group 11. But we know that they are all a part of group 3
hello Roshni Mam, I desperately Want you to make videos on the organic remaining chapter and inorganic chapter (metallurgy), plus mam your teaching style is way more than perfect in you explain in a very short period, it's a request mam
8:00 i have made my own memory tip :---- 1. FOR LANTHANOIDS Seene par nadiyan prem ki samayein eun gad tab dil hua aur tum abb laute. 2. FOR ACTINOIDS Thapa you neplai purane aam kam bikenge cafe mei esse farmo madam nosta laoo kaisa lga memory tip ? please btao
I will suggest that when you watch lectures of mam then also open your NCERT book and keep it on side because mam leave many topics , so you can therefore learn them from book.
Mam aap pichle video main bole the ke coloured ion partially filled d-orbital ke wajah se dikhta hain par aabh aap 21:52 main bole ke f orbital. .... Plzz reply 😢
Because lantanoids and actinoids are f block elements... So in f block elements colour of ion depends upon no of unpaired electrons in (n-2)f orbital..
Mam Please class 12th COORDINATION COMPOUND, ALDEHYDES KETONES AND CARBOXYLIC ACIDS, AMINES ki videos bhi as soon as possible upload kr di jiye. 🙏🙏 CHEMESTRY CLASS 12 BOARD h 7th MAY ko. 🙏
Mam pls make the video on the topic amines bcz our preboard is approaching very soon And apka videos are really awsm With ur one shot , we don't need to study from NCERT Bcz u teach each and every point and concept of NCERT..in short Really helpful Mam pls upload carboxylic acid and amines Huge demand from your student
Ma'am because of you students get all the knowledge of the concepts for free and nothing Will left in your explanation. In fact extra, you provides us. Thanks for your help and in last you are the greatest teacher of all the subject's. Jai Hind 👏🤚
