Glucose is a covalent compound. This means that the bonds between the atoms in a glucose molecule are formed by the sharing of electrons, rather than the transfer of electrons as seen in ionic compounds.
Glucose (C6H12O6) is made up of carbon, hydrogen, and oxygen atoms. These atoms share electrons to form covalent bonds. For example, each carbon atom in glucose forms four covalent bonds with other atoms, and each oxygen atom forms two covalent bonds. This sharing of electrons allows the atoms to achieve a stable electron configuration.
In contrast, ionic compounds are formed when one atom transfers electrons to another, resulting in the formation of positively and negatively charged ions that are held together by electrostatic forces. Since glucose does not involve such electron transfer, it is classified as a covalent compound.
