What are the types of chemical bonds in citric acid, Sodium Chloride, and Sucrose

-Sodium chloride is composed of a metal and nonmetal so it is ionic. Both citric acid and sucrose are composed of C, H and O all nonmetals so these are covalently bonded. Nonmetals with other nonmetals are covalent because even the more electronegative element cannot completely pull the electrons off the second (or third) element so the result is electron sharing (a covalent bond). Metals hold their valence electrons relatively loosely, so a non metal can completely capture that electron to form ions.......
