How do we differentiate between a molecular element, and a molecular compound? And how are these differentiated from non-molecular species?
Answers
Answer:
A molecular element is a molecular substance consisting of a single element, such as H2, F2, Cl2, Br2, I2, O2, O3, P4, S8.
Binary molecular compounds are composed of only two elements Molecular compounds are more difficult to name because the atoms combine through covalent and not ionic bonds. Therefore we cannot use the electrical neutrality rule for these compounds. Most molecular compounds are made from nonmetals.
A chemical species is a chemical substance or ensemble composed of chemically identical molecular entities that can explore the same set of molecular energy levels on a characteristic or delineated time scale. The term is applied equally to a set of chemically identical atomic or molecular structural units in a solid array
