Hi, student.
00:01
First of all, thanks a lot for posting the problem.
00:03
Let me welcome you with a smile.
00:05
Here, the compound that is given in the question is a coordination compound, which is indicated by the square brackets.
00:25
And we have, the components are a metal ion and a ligand.
00:37
Here, cobalt ion is the metal ion and ammonia is the ligand.
00:50
This is neutral.
00:53
So all the charges, that is 3 plus, is actually the charge of the metal ion cobalt.
01:04
So in this coordination compound, the charge of cobald ion is 3.
01:14
3 plus.
01:17
Now the atomic number of cobald is 27 considering the 3 plus charge the number of electrons in cobald ion is 20.
01:40
Now let us write the electronic configuration related to these number of electrons...
