Writedown the number of 3d electrons in each of the following ions:
Ti2+,V2+,Cr3+,Mn2+,Fe2+,Fe3+,CO2+,Ni2+and Cu2+.
Indicatehow would you expect the five 3d orbitals to be occupied for thesehydrated ions (octahedral).
Metal ion | Number of d-electrons | Filling of d-orbitals |
Ti2+ | 2 | |
V2+ | 3 | |
Cr3+ | 3 | |
Mn2+ | 5 | |
Fe2+ | 6 | |
Fe3+ | 5 | |
CO2+ | 7 | |
Ni2+ | 8 | |
Cu2+ | 9 |
