Sir to calculate sigma of Zn in 4s orbit why did you multiply 18 with 0.35 and not 0.85?
In the video u said biunoctium(218) which is a noble gas just below this element which hypothetical noble gas will come . u said add magic number 98 in 218 and answer will be 316. But u mentioned 290 there?? ? How could be possible
Sir am confused that total no of elements in Periodic table if there are 10periods in period table I think acc to videos answer will be 290 but here answer is 72 plss explain me how ??
