Is Mgl2 Magnesium iodide or Magnesium Chloride, I am confused
I is Iodine
Cl is Chlorine
it's iodine, you're first option. Magnesium Iodide
To determine whether Mgl2 refers to magnesium iodide or magnesium chloride, we can follow these steps:
Step 1: Identify the elements involved
In this case, we have "Mg" and "l".
Step 2: Determine the valency of "l" and the common valency of magnesium
The common valency of magnesium is 2 because it is an alkaline earth metal.
The valency of "l" can be found by locating it on the periodic table. Since "l" is the 53rd element, it corresponds to iodine (I), which has a valency of -1.
Step 3: Assign the valencies to the elements in the compound
Given that magnesium has a valency of 2 and iodine has a valency of -1, the formula Mgl2 can be interpreted as:
Mg2+ (from magnesium) + 2I- (from iodine).
Step 4: Identify the compound
Combining the valencies of the elements, we can conclude that Mgl2 represents magnesium iodide. The 2+ charge of the magnesium cation (Mg2+) balances the 2- charge of the two iodide anions (2I-), resulting in a neutral compound.
Therefore, Mgl2 stands for magnesium iodide, not magnesium chloride.
