CBSE Class 9 Answered
Respected Sir/Madam,
We have the formula 
where n is no. of shell which gives us the maximum no. of electrons the shell can accomodate . If an atom has 5 shells then the outermost shell will have 50 electrons according to the formula but this contradicts the rule that outermost shell can only have maximum no. of 8 electrons. Please explain...

Expert Answer
The fifth energy shell has 50 electrons (s, p, d, f, g subshells).
p subshell = 6 electrons
d subshell = 10 electrons
f subshell = 14 electrons
g subshell = 18 electrons
Hence total 50 electrons in the fifth energy level, which confrms 2n2 formula.

ANSWERED BY EXPERTCBSE 9 - Chemistry
. Then i have to first react Carbon with Oxygen then react that compond with calcium. So how will i know the valency of compound formed from reaction of carbon with oxygen. We can know the valency of elements from their atomic number and electronic configuration, but how can i know the valency of compound?
Please help,waiting for your reply,
Thank you. Asked by hk.sachdev | 12 Oct, 2018, 10:38: PM
