Lewis structure

The Lewis Structure of D-Glucose consists of 6 carbon elements, 6 hydrogen elements, and 12 hydrogen elements. The molecular formula of D-Glucose is C6H12O6. The Lewis Structure consists of single bonds between the elements, meaning that the when the valence electron level of one element isn't full, it pairs up with another element that either needs to loose or gain an electron to make the atom more stable.
