Which one of the following is most likely to be a covalent compound_

  • The example given above is of a very familiar compound called HF. The % ionic character is nearly 43.25%, so the % covalent character is (100 – 43.25) = 56.75%. But from the octet rule HF should have been a purely covalent compound but actually it has some amount of ionic character in it, which is due to the electronegativity difference of H and F.

  • To recognize molecules that are likely to have multiple covalent bonds. In many molecules, the octet rule would not be satisfied if each pair of bonded atoms shares two electrons. Consider carbon dioxide (CO 2 ). If each oxygen atom shares one electron with the carbon atom, we get the following: 4.2: Multiple Covalent Bonds - Chemistry LibreTexts
  • The periodic table can help us recognize many of the compounds that are ionic: When a metal is combined with one or more nonmetals, the compound is usually ionic. This guideline works well for predicting ionic compound formation for most of the compounds typically encountered in an introductory chemistry course.

  • Dec 25, 2007 · HCl is a covalent compound. There is more than one step to this process. From the name of the compound, you have to be able to figure out whether you have metal and nonmetal combined with one another, in which case you would have an ionic material, or whether you have only nonmetals, in which case you generally have covalent bonding.
  • Well, elements that form covalent bonds are non-metal elements. I don’t know if metalloids also do that or not, though. Group IIIB, IVB, VB, VIB, VIIB, VIIIB, IB, and IIB (3–12 in the picture) are all metals, so they’ll never form covalent bonds. ...
  • Ionic and Covalent Bonding. Chapter 9. Lewis Electron-Dot Symbols. A Lewis electron-dot symbol is a symbol in which the electrons in the valence shell of an atom or ion are represented by dots placed around the letter symbol of the element.
