why does the electronic configuration of fe3+ has 4s0
(electronic configuration of Fe 3+ is [ar] 4s0 3d5)

Atomic number of Fe is 26. That is, it has 26 electrons. d subshell can occupy 10 electrons (in 5 orbitals). ... As the atomic no. of iron is 26 so its electronic configuration will be 1s2 2s2 2p6 3s2 3p6 3d6 4s2.After loosing 3 electrons its electronic configuration will be is2 2s2 2p6 3s2 3p6 3d5 4s0.

why does 2 electron get removed from s orbital 1 from d orbital and not directly 3 from d orbital itself??
sorry its a mistake
don't mind

Electron configuration of
Fe- 4s2 3d6
since 4s is far from nucleus than 3d. electron in 4S is in 4th orbit which is far from 3rd orbit. consequently electron will remove from 4S orbital then 3D orbital.
Fe+ - 4S1 3d6
Fe2+- 450 3d6
Fe 3+ 4S0 3d5
I hope it will help you
thank you!!
maybe if possible can you send thise attachments via email?

24 Cr -- {Ar]4S2 3d4 , again apply same principle Cr + -[Ar] 4S1 3d4, or some time write 4S0 3d 5, Cr2+ =4s0 3d4
thank you ive got it
one last question
while finding de broglies wavelength is it okay to round off the final decimal answer to its nearest whole number??
yes you can do up to one or two decimal place.
like rounding 1.017 to 1
to nearest whole number or integer
1.017 may write 1.02 but its a very small wave length no need to do
