Oct 24, 2020 · A compound consists of two or more elements chemically bonded in a fixed ratio. All compounds are examples of molecules, but molecules also include substances consisting of only one element, chemically bonded to itself. In chemistry, a compound is a substance made of two or more elements chemically bonded to each other in a fixed ratio.
Oct 17, 2020 · By this definition, O 2 would be an element, a molecule, and a compound. Because of differing definitions, chemistry teachers probably ought to stay away from questions about elements/compounds and simply focus on the 118 elements of the periodic table as examples of elements. References. Burbidge, E. M.; et al. (1957).
The difference between an element and a compound is that an element is a substance made of same type of atoms, whereas a compound is made of different elements in definite proportions. Examples of elements include iron, copper, hydrogen and oxygen. Examples of compounds include water (H 2 O) and salt (Sodium Chloride - NaCl).
