Answer:
i want to say nuclues but again i also think that it is electron shells
Octahedral is the geometry of the complex ion which has d2sp3 hybridization.
The octahedral has eight faces hence the prefix octa. Octahedral molecular geometry describe the shape of compound with six atom or groups of atoms or ligands symmetrically arranged around a central atom.The octahedron is one of the platonic solids.
The spoon should be connected to the negative terminal of the battery. The other electrode should be made of silver.

<h3>Explanation </h3>
+ 2 e⁻ → 
It takes two moles of electrons to reduce one mole of cobalt (II) ions and deposit one mole of cobalt.
Cobalt has an atomic mass of 58.933 g/mol. 0.500 grams of Co contains 
of Co atoms. It would take 
of electrons to reduce cobalt (II) ions and produce the 
of cobalt atoms.
Refer to the Faraday's constant, each mole of electrons has a charge of around 96 485 columbs. The 0.01697 mol of electrons will have a charge of 
. A current of 0.961 A delivers 0.961 C of charge in one single second. It will take 
to transfer all these charge and deposit 0.500 g of Co.
