Vitamin D is important for maintaining a healthy body, primarily because it helps you fully maximize your body’s absorption and utilization of calcium, an important mineral that we all need.Halide minerals are salts that form when salt water evaporates. Halite is a halide mineral, but table salt is not the only halide. The chemical elements known as the halogens (fluorine, chlorine, bromine, or iodine) bond with various metallic atoms to make halide minerals (see Figure below).This leads them to form the crystal lattice of the mineral halite. Halite is a mineral with the chemical formula NaCl, sodium chloride, in which the bonds between the atoms are all ionic bonds. Look at the diagram of halite showing the sodium and chloride ions arranged into the crystal lattice.Gold has a density of about 19 g/cm 3; pyrite has a density of about 5 g/cm 3 —that’s another way to tell pyrite from gold. Quartz is even less dense than pyrite and has a density of 2.7 g/cm 3. The specific gravity of a substance compares its density to that of water.
