What element has the atom whose K,L, and M shells and 4s subshell are filled completely and 4p subshell is half-filled? |
|
Answer» SOLUTION :The order of filing is `K,L,M` shells, then `4s^(2),3d^(10)` then `4p^(3)`. Theelectronic configuration of the element will `1s^(2)2S^(2)2p^(6)4s^(2)3d^(10)2p^(3)` (There must be three `4p` electrons) The number of ELECTRON is `Ƶ=33` and the element is As (The `3d` subshell must be FILLED before `4p` fills up.) |
