However, when you really look at the evidence, it becomes clear that they are in fact covalent. In the case of covalent compounds, electrons are not completely dragged, the atoms of different elements are attracted by a weaker electrostatic force. Heteronuclear atoms with an electronegativity difference < 1.5 are considered mainly covalent bonds. This could mean that the electrons are attracted to the nucleus, which would make cornstarch ionic. The chemical formula for corn starch is C27H48O20, which shows that it is made up of carbon and oxygen, two nonmetals, and hydrogen, which behaves like a nonmetal in chemical reactions.
