You probably think to anhydrous magnesium carbonate and hydrated magnesium carbonates:
MgCO3, MgCO3.2H2O, MgCO3.3H2O, MgCO3.5H2O
No. These are not heavy metals. They are salts of non heavy metals.
Grams is How Heavy it is Liters Is the way we measure Meters are a measurement
Scientifically speaking, there are a couple of fundamental differences between heavy metals and other metals in the table of the elements. Heavier metals tend to have more ions and typically, less toxic elements.

light crude oil has less specific gravity,less viscosity while heavy crude oil has more specific gravity & viscosity.
Magnesium is not a heavy metal.
