Oxidation state is the number assigned to an atom of an element in a compound which represents the number of electron gained or loss by it positive oxidation state signifies the loss of electrons and negative oxidation state signifies gain of electrons so in complex co and h36 cl3 there are three c .l atom ions.

The central atom is a transitional metal, cobalt, transition metal, transition metal, which is attached to six ammonia molecules.
01:05
The oxidation state of ammonia is zero.
01:08
Let the oxidation state of co be x, then x plus 6 multiplied by 0 is equal to plus 3, which is equal to x is equal to 3.
01:27
Thus the oxidation number of, thus the oxidation number of, thus the oxidation number of cobal.
01:38
Is plus three the atomic number of atomic number of of cobalt is 27 and its electronic configuration is ar argon 3d 7 4 s in plus 3 oxidation state it's so in plus 3 oxidation state the electronic configuration would be ar 3d 6 4 s 0 therefore the number of d electrons therefore number of d electrons in cobalt 3 plus is 6 the outermost electronic arrangement of outermost electronic arrangement of arrangement of cobalt 3 plus is 3d orbital 1 2 3 4 5 6 3d orbital 4 and 4p is also 0.
