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.
Aluminium chloride is a covalent bond. Actually, it is a ionic bond with a higher degree of covalency. This is due to polarization. Cations are very polarizing, while anions a â¦ re very polarizable. The higher the charge of the cation will increase the degree of distortion of the electron cloud surrounding the anion.ilver oxide (AgO) would have ionic bonds, as this is a bond between a metal and a nonmetal which tends to favor the formation of ionic bonds over covalent bonds. + 4 others found this useful.
