Expert Answer
(a) Bohr Bury Rules:
(i) The maximum number of electrons present in a shell is given by the formula 2n2 (where n is shell no.)
(ii) The maximum number of electrons that can be accommodated in the outer most orbit is 8.
(iii) Electron are not accommodated in a given shell, unless the inner shells are filled.
(b)
(i)Element X: At No. = 17; E.C = 2 , 8, 7
(ii) Element Y: At. No.= 16; E.C. = 2, 8, 6

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
