Indole is an aromatic heterocyclic organic compound with formula C8H7N. It has a bicyclic structure, consisting of a six-membered benzene ring fused to a five-membered nitrogen-containing pyrrole ring. Indole is widely distributed in the natural environment and can be produced by a variety of bacteria. As an intercellular signal molecule, indole regulates various aspects of bacterial physiology, including spore formation, plasmid stability, resistance to drugs, biofilm formation, and virulence.

Â· just now. Report Abuse. monatomic means there is only one atom. a monatomic ion is an ion that consists of one atom with either excess or a lack of electrons and it has either a negative or a positive charge. Some examples of monatomic ions are Cl(-) and Mg(2+).hus, Na+ is a monatomic ion, whereas NH4+ is not. Anything with a charge (that is, anything that is not neutral or 0 charge) is an ion. Mg2+ is more charged than Na+. A molecule is diatomic if it has two atoms (which could be the same or different), triatomic if it has three atoms, and so on so forth.
