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.
Potassium Chloride. Potassium chloride, which is shown as KCl, is an ionic solid. It is in the form of a white color, odorless crystal. The crystal structure of this is a face-centered cubic structure.odium and potassium are group 1 metals, which have the capability to make +1 cations. Chloride is the -1 anion made by group 7 element, chlorine. Since group 1 elements are electropositive and group seven elements are electronegative, their electronegativity difference is larger. So they form ionic bonds.
