The previous chapter video was best, but this chapter video is not so good, you are skipping the topics, not going into deep, I request you to cover chapters in the same way that you had done with ch2. I know it's more difficult and time consuming but it is also very effective. Thank you

[@jayprabhavyas11]

ma'am why didn't you highlight the BORON in the category of metalloids,Boron is neither a metal nor a non-metal; it is kept in the category of metalloids. Metalloids are generally those compounds whose properties are in between metal and non-metal or we can say that they have mixed properties of both metal and non-metal.

Mam when we add 18 in Xe 54 atom the n we didn't get Rn 86😢 This contradicts your theory

[@anilguptta1908]

When we talk about noble gases, we skip 2 in the order 2-8-8-18-18-32. So, the order for noble gases becomes-8-8-18-18-32. So,--> He=2 -->Ne=10 (2+8) -->Ar=18 (10+8) -->Kr=36 (18+18) -->Xe=54 (36+18) --> Rn=86 (54+32) Hope it clears your doubt.
