the VSEPR model utilizes electron-pair geometry (regions around the central atom) and molecular geometry (amount of lone pairs around the central atom–so whatever the electron-pair geometry is, you just count the amount of lone pairs in those regions).
Explanation:
No lone pairs around the central atom, the electron pair and molecular geometry would be the same. Bond angle differs depending on the electron pair geometry and molecular geometry you have for a molecule.
<h3> <em>Aluminum would be the best choice to reuse copper from the copper chloride solution because it In the aluminum–copper reaction, the chloride ions help remove the aluminum oxide coating so that a reaction can take place through the oxidation of aluminum and the reduction of copper ions.The aluminum–copper chloride reaction is a simplified version of a waste reclamation and reduction strategy for handling toxic-waste materials. </em></h3>
