WebMonosaccharides have a formula of (\text {CH}_2\text O)_n (CH2O)n, and they typically contain three to seven carbon atoms. [How is that formula different from carbohydrates in general?] Most of the oxygen atoms in monosaccharides are found in hydroxyl ( \text {OH} OH) groups, but one of them is part of a carbonyl ( \text C=\text O C = O) group. WebA molecule is the smallest isolable form of a compound, but ionic compounds depend on the crystal structure and you cannot make a salt crystal without many sodium ions and chloride ions arranged in a crystalline lattice. The same, by the way, is true of metals: they depend on the lattice of nuclei and electrons for their stabiility. the kirpan
