BaCl2 has the greatest ionic character. According to Fajans’ rule, a compound with low positive charge, large cation and small anion has ionic bond where as a compound with high positive charge, small cation and large anion has covalent bonds. Lower the covalent character, higher will be ionic character.Click to see full answer. Also know, which compound contains ionic bonds? Ionic bond examples include: LiF – Lithium Fluoride. LiCl – Lithium Chloride. LiBr – Lithium Bromide. LiI – Lithium Iodide. NaF – Sodium Fluoride. NaCl – Sodium Chloride. NaBr – Sodium Bromide. NaI – Sodium Iodide. Furthermore, how do you find the greatest ionic character? To find the ionic character (or the polarity) of a bond, we look at the electronegativity of the two atoms involved. The greater the difference, the more ionic character in the bond. Subsequently, one may also ask, which compound contains a bond with the least ionic character? Br-Cl has the least ionic character of the 4 options. It is close to a pure covalent bond. Ionic character is determined by the difference in electronegativity in the atoms participating in the bond. The greater the difference in electronegativity, the greater the ionic character of the bond between them.Which substance is an ionic solid?Examples of ionic solids include NaCl and Ca(CO3). Ionic compounds are all generally found in nature as ionic solids.
