According to Bohr-Bury rules, what are the conditions for the filling of electrons in:
i. A new shell
ii. A penultimate shell and outermost shell
Asked by Topperlearning User | 13 May, 2014, 01:15: PM
Expert Answer
i. Electrons are not accomodated in a new shell unless the inner shells are completely filled.
ii. The outermost shell cannot hold more than 2 electrons and the penultimate shell cannot hold more than 9 electrons unless the preceding inner shell is filled with its maximum number of electrons.

. 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
