Your chemistry videos are awesome. Love them. Can u make a video on nomenclature??
Thanks sir for such a really really wonderful video. I find chemistry a non scoring subject coz my basic concepts are not clear. This video has helped me a lot in understanding the basics of chemistry. This video has helped me a lot in understanding the periodic table of elements which I thought I never ever could. Keep uploading such wonderful videos for students like us
This is the best video I've found that explains the periodic table clearly. Thanks very much for uploading.
Great but what about metalloids, actinoids, ;anthanoids, and transition metals
