Question

write a electroninc configuration of Sn+4 in form of s,p,d,f

Answer 1

Normal Sn configuration is

1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6

5s2 4d10 5p2.

(In filling order. Not removing order of electrons)

Sn 4+ means after removing outermost 4 electrons of 5th shell

Therefore Sn 4+ -- 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 4d10 ( 5s0 5p0)
