Question

a which of the following electronic configuration are not possible ? given reason (1), x-2, 8, 4 , (2), y- 3, 8, 2 , (3) z-2, 8, 9

Answer 1

in (3) electronic configuration is not possible because the number of electrons which can be present in the outermost shell is 8 but here it is 9 . so here electronic configuration is not possibe.

Answer 2

Answer:3 electronic configuration is not possible because the number of electrons which can be present in the outermost shell is 8 but here it is 9 . so here electronic configuration is not possibe.
