Since MgCO3 is a ionic bond it is not a polar molecule (only has covalent bonds). Explanation: MgCO3 shows ionic bonding between Mg 2+ and CO 3 2-but simultaneously covalent bonding exists between C and O in case of CO 3 2-. No. Methane: CH4 Carbon Dioxide: CO2 Carbon Tetrachloride: CCl4 Sodium Chloride: NaCl Potassium Permanganate: ? I already tried Google to no avail Are the following compounds ionic or covalent? MgCO3 shows ionic bonding between Mg 2+ and CO 3 2-but simultaneously covalent bonding exists between C and O in case of CO 3 2-. Where can I find this? Since MgCO3 is a ionic bond it is not a polar molecule (only has covalent bonds). Hence both ionic and covalent bonds exist. I need the # of valence electrons, ionic or covalent bond, # of protons, neutrons, and electrons Can someone help!? CaCO3 Ca-O- is Ionic where as CO3 is Covalent. If its metal and non-metal or metal-metal the you get Ionic. E.g. A. NaCl B. Cl2 C. MgO D. MgCO3 E. None on these I can't find this information anywhere. No. Calcium Carbonate: CaCO3 Lithium Hydroxide: LiOH Sodium Nitrate: NaNO3 Magnesium Oxide: MgO Ammonium Hydroxide: NH4OH Silver Iodide: AgI Magnesium … Some are both, because you have a metal and non metal, plus non-metals interacting with non-metals. Which of the following substances has both ionic and covalent bonding? Also, does anyone know the formulas for the 2 compounds missing them?
