👉 In chemistry, a semimolecule is a molecule that contains an atom of one element and has no atoms of another element. This means that it can be considered as a single atom in its entirety, with only one type of electron configuration (2n+1), where n is the number of electrons present in the molecule. Semimolecules are often used in organic chemistry to model biological molecules or to study chemical reactions involving proteins and other macromolecules. They are also important for understanding the structure
