Is iron oxide a molecular or ionic compound?

Iron as an ion can have +2 or +3 as its oxidation state. When forming compounds with oxygen (almost always with an oxidation state of -2), the compounds formed could be FeO, Fe2O3, or Fe3O4. So iron oxide is a polar covalent compound with ionic character.

Is nh3 an ionic compound?

NH3, also known as ammonia is a covalent compound. Reason being: Hydrogen and Nitrogen are both non metals and do not have the tendency to donate their electrons, which is a necessary condition for ionic bonds, as a result ionic compund is not possible.
  • Is h2o an ionic or covalent compound?

    H2O or water as it is more commonly known as is a molecule consisting of 2 Hydrogen molecules bonded to one Oxygen molecule. As the table shows this makes H2O a molecule with a polar covalent bond. Well, electronegativity is the measure of how attracted bond seeking electrons are to an element.
  • Is b2h4 ionic or covalent?

  • Is water an ionic or covalent bond?

    There are "in between" states like polar covalent, where one side of the bond is stronger but not fully ionic. And this I think is the main reason: hydrogen has fairly high Pauling electronegativity (2.20), rather close to oxygen (3.44), which seems polar covalent overall (and why we get hydrogen bonding with water).

Is HBR an ionic or covalent compound?

It is best to think of all hydrogen halides as covalent polar molecules, with the polarity increasing in the order HI < HBr < HCl < HF, as suggested by the electronegativity differences. If every ionic compound is solid at 298K, the first answer is right. I mean, those molecules you mention would not be ionic bonded.
  • Is alcl3 ionic or covalent?

    Size of chlorine being greater than fluorine, AlCl3 is covalent while AlF3 is ionic. Fajan's rule states that, small size of cation and large size of anion, greater is the covalent character of the ionic bond. In between AlCl3 and AlF3, cation (Al) is the same both the compound. Hence AlCl3 becomes covalent.
  • Is nacl ionic or covalent or both?

    A molecule or compound is made when two or more atoms form a chemical bond that links them together. Ionic bonds usually occur between metal and nonmetal ions. For example, sodium (Na), a metal, and chloride (Cl), a nonmetal, form an ionic bond to make NaCl. In a covalent bond, the atoms bond by sharing electrons.
  • Is so2 an ionic or covalent compound?

    It form. Covalent bond because Each oxygen atom shares two valence electrons with sulfur. SO2 is covalent since it is formed by the sharing of electrons between sulphur and oxygen.
