[Co(NH3)JCO3]CIO4 Six monodentate ligands are attached to Co hence C. N. of Co = 6;
O. N. = x + 5 x (0) +1 x (-2) +1 x (-1) = 0
∴ x = + 3 ; electronic configuration of Co3+[Ar] 3d64s0
hence the number of d electrons is 6 : All d electrons are paired due to strong ligands hence unpaired electrons zero.

Consider the following complex [Co(NH3)5CO3]ClO4.The coordination num...
The given complex is [Co(NH3)5CO3]ClO4.
Coordination Number:
The coordination number of a metal complex is the number of ligands attached to the central metal ion. In this complex, there are six ammonia (NH3) ligands attached to the central cobalt (Co) ion. Therefore, the coordination number is 6.
Oxidation Number:
The oxidation number of an element indicates the number of electrons it has gained or lost in order to achieve a stable electron configuration. To determine the oxidation number of cobalt in the complex, we consider the charge of the complex and the charges of the other ligands. The perchlorate ion (ClO4-) has a charge of -1. Since there is one ClO4- ion in the complex, the overall charge of the complex is -1. The total charge of the ammonia ligands is 0 since ammonia is a neutral molecule. Therefore, the cobalt ion must have a +1 oxidation state to balance the overall charge of the complex. Hence, the oxidation number of cobalt is +1.
Number of d-electrons:
The cobalt ion in this complex is in the +1 oxidation state. To determine the number of d-electrons, we need to refer to the electron configuration of Co+1. The electron configuration of cobalt in its +1 oxidation state is [Ar] 3d6. Therefore, the number of d-electrons is 6.
Number of unpaired d-electrons:
To determine the number of unpaired d-electrons, we need to consider the electron configuration of Co+1. In the case of cobalt, the 3d subshell can accommodate a maximum of 10 electrons. Since cobalt in the +1 oxidation state has 6 d-electrons, there are 4 unpaired d-electrons.
Therefore, the correct answer is option A: 6, 3, 6, 0.
Coordination Number:
The coordination number of a metal complex is the number of ligands attached to the central metal ion. In this complex, there are six ammonia (NH3) ligands attached to the central cobalt (Co) ion. Therefore, the coordination number is 6.

Therefore, the cobalt ion must have a +1 oxidation state to balance the overall charge of the complex. Hence, the oxidation number of cobalt is +1.

Therefore, the correct answer is option A: 6, 3, 6, 0.
