The term "heavy atom" is used to refer to any atom in a molecule that is not a hydrogen atom. In other words, heavy atoms are those that have higher atomic weight than hydrogen which has an atomic number of 1. These atoms may include carbon, nitrogen, oxygen, sulfur and many other elements. The concept of heavy atom is often used in the context of nuclear magnetic resonance (NMR) spectroscopy, where the presence of heavy atoms in a molecule leads to a larger coupling constant and shorter relaxation times, resulting in clearer and more accurate spectroscopic data. Therefore, the distinction between hydrogen and heavy atoms is an important one in the field of chemistry.What is the count of heavy atoms present in the molecule?
