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.
Yes it does have an ionic bond. Yes, sodium chloride does have an ionic bond. Sodium chloride, table salt, NaCl is an ionic compound formed by the elements Sodium - Na and Chlorine - Cl. For both elements to obtain a full outer shell (8 electrons) and form an ion, Sodium would have to LOSE an electron and Chlorine would have to GAIN an electron.
