Hi! Did you use the Method A and B?

[@saitamasensie4968]

Great

Thank you.

Hi could u pls do it with electron configuration like explain what does exactly happen with electron configuration of the metal & Cl ?

[@Chemistryuniversity]

The metal will use its d orbitals to interact with the ligands. Halogens will use primarily p orbitals to interact with transition metals. These orbitals are the closest in energy, therefore they are most likely to interact. We can think of this as either a covalent interaction or ionic (halogens are considered to be a negatively charged ligand due to their higher electronegativity). If we are counting using the covalent system, then the metal will be neutral (having its original electron configuration) and the halogen will contribute 1 electron to the count. Ionic counting method will use electron configuration of the ion and then the halogen will contribute 2 electrons. Both systems will yield the same electron counts.

You have such a nice pen

[@Chemistryuniversity]

It is a Sheaffer calligraphy pen. I use a larger nib (wider) pen for the titles. In my more recent videos I use a glass (pyrex) pen.

Thank u sir ❣️👍

Cobalt isn't +3 it's +2

[@Chemistryuniversity]

In these complexes cobalt is +3. Cobalt has two common oxidation states: +2 and +3.
