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.
Chloride is a monovalent ion with -1 charge. Therefore, it has 18 electrons and seventeen protons. The electron configuration of chloride is 1 s 2 2 s 2 2 p 6 3s 2 3p 6. Chloride exists in ionic compounds such as sodium chloride, calcium chloride and HCl, which are ionic. Chloride has achieved the Argon electron configuration, therefore, stable than the chlorine atom. â¢ Chloride ion is attracted to positively charged electrodes or other positively charged chemical species, but chlorine does not.
