Barium is an element, derived primarily from the mineral barite, and used as a heavy additive in oil-well-drilling mud, paints, rubber, plastic and paper; production of barium chemicals; and glass manufacturing.ercury is extracted from the mineral cinnabar and is used in electrical products, electrolytic production of chlorine and caustic soda, paint, and industrial and control instruments (thermometers and thermostats). Mica. Mica minerals commonly occur as flakes, scales, or shreds.
If the electronegativity difference is between 0 and 0.2, it is a nonpolar covalent bond. If the electronegativity difference is between 0.2 and 1.4, it is a polar covalent bond. If the electronegativity difference is greater than 1.4, it is an ionic bond. Calcium is 1.3, Chlorine is 3.0, for a difference of 1.7. Calcium Chloride is an ionic compound.
Formula and Structure of Calcium Chloride. Calcium chloride is created from the ionic bonds that form between calcium cations and chloride anions. Calcium ions have a charge of +2, while chloride ions have a charge of -1. The molecule for calcium chloride has one calcium ion (+2) and two chloride ions (-1), which means that the overall charge for the molecule is 0, or neutral. On screen is the chemical reaction for the formation of calcium chloride.
