It depends on the chemical reaction taking place.
If magnesium iodide is on the left-hand side of the equation it is a reactant.
If magnesium iodide is on the right-hand side of the equation it is a product.
From Wikipedia:
"The substances initially involved in a chemical reaction are called reactants. Chemical reactions are usually characterized by a chemical change, and they yield one or more products, which usually have properties different from the reactants."
It can be either depending on the reaction.
For example, in the reaction
Mg + 2HI --> MgI2 + H2
magnesium iodide is a product.
However, in the reaction
MgI2 + Pb(NO3)2 --> Mg(NO3)2 + PbI2
magnesium iodide is a reactant.
MgI2 is also known as Magnesium Iodide. This is a molecule of magnesium that is bonded to two molecules of iodine.
Magnesium Iodide You don't have to say that it is magnesium (II) iodide because it is already apparent that the charge is 2+
Magnesium Fluoride. It's an ionic compound.
When the limiting reactant is completely used up. A limiting reactant is the reactant that determines the amount of product. To determine this use the balanced chemical reaction with the masses of the reactants to determine the moles of product formed. The reactant that forms the least amount of product will be the limiting reactant.
Mg2+ + 2I- ---> MgI2
A reactant exists at the beginning of a chemical reaction whilst a product exists at the end. They are alike in the fact that to get to a product you need to have a ready supply of the reactants. An example of a simple reactant/product reaction is shown below. Magnesium + Oxygen --> Magnesium Oxide Reactant + Reactant --> Products Hope this helps

There are magnesium ions and iodide ions in magnesium iodide.
Sugar can be both a reactant and a product.
