Try to untie the knot from the balloon let some air out and tie if back....
Coordination number is the number of ligands either neutral or anionic surrounding the Metal atom in complex.
Here Coordination number is 5, means five NH₃ are attached to Ni atom.
[Ni (NH₃)₅]
The charge on sphere is the charge carried by Ni atom which is +2.
So,
[Ni (NH₃)₅]⁺²
Pentaamine Nickle (II) Ion
<span>because if there is the same amount of atoms on the reactants and the products obviously none is lost :)</span>
