Nonmetals form negative ions (anions). Is cornstarch ionic or molecular? /Subtype /Image >> Cornstarch is classified as a covalent bond as well due to its chemical formula and most of the results from the experiments. 5) Low Solubility Many covalent compounds are not soluble in water, which means that they do not dissolve well in water. The Cation is Na+1 and the Anion is C7H5O2-1. Ionic bonds are electrostatic forces of attraction, that is, the attractive forces experienced between objects of opposite electrical charge (in this case, cations and anions). Corn starch is covalent because it doesn't dissolve in water, and is not a crystal. In solid form, an ionic compound is not electrically conductive because its ions are unable to flow (electricity is the flow of charged particles). For example, when each sodium atom in a sample of sodium metal (group 1) gives up one electron to form a sodium cation, Na+, and each chlorine atom in a sample of chlorine gas (group 17) accepts one electron to form a chloride anion, Cl, the resulting compound, NaCl, is composed of sodium ions and chloride ions in the ratio of one Na+ ion for each Cl ion. If the anion present is polyatomic then the only name of polyatomic anion is used without suffix 'ide' in the end.
