HgI2 (with the '2' small subscript - ie below the line)
Mercury Iodide
Mercury (I) Iodide.
When Mercury and Iodine are ground together, a compound called Mercury(I) Iodide is formed with the chemical formula Hg2I2 but this compound is sensitive to light and will break down into elemental Mercury and Mercury(II) Iodide with the chemical formula HgI2 .Interestingly, Mercury(II) Iodide changes color with changes in temperature, changing from orange at room temperature to yellow above 126 degrees Celsius due to a change in crystal structure.
BaI2 is the chemical formula for Barium Iodide.
