Definition: A monosulfide is a compound consisting of two sulfur atoms bonded together. Monosulfides are formed when sulfur reacts with another element, such as oxygen or nitrogen. They can be classified into two main types based on their structure: diamagnetic and paramagnetic. Diamagnetic monosulphides have an electric dipole moment due to the presence of a magnetic field around the molecule, while paramagnetic monosulfides do not have an electric dipole moment but instead have a
