Can an element consist of molecules?
Molecules are made of atoms, and most molecules are made up of atoms of two or more elements. They are combined in any of several ways, held together by ionic or covelent molecular bonds. Molecules may also consist of a single element which forms diatomic or triatomic forms (allotropes). An example is oxygen, which is primarily diatomic but can exist as a three-atom molecule called ozone. Some molecules are very large, containing hundreds of atoms.
Some are, some are not. There are four kinds of carbohydrates, or sugars: Monosaccharides consist of one molecule (examples include glucose, fructose, galactose, xylose, ribose, etc.) Disaccharides consist of two molecules (examples include sucrose, lactose, maltose, etc.) Oligosaccharides consist of a few molecules (examples include fructo-oligosaccharides, galactooligosaccharides, mannan oligosaccharides, etc.) Polysaccharides consist of many molecules (examples include starch, glycogen, cellulose, pectins, etc.)
