Can electrons be arranged in second shell or L shell without filling the first shell or K shell?
Asked by Topperlearning User | 13 May, 2014, 02:01: PM
Expert Answer
No, because electrons are filled first in shells having lower value of energy, the energy of first shell is lower than second shell. So, electrons will be arranged first in the K shell i.e. the first shell.

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
