👉 In computational chemistry, a percompound is a chemical compound that is composed of two or more atoms with identical atomic numbers. This means that each atom in the percompound has the same number of protons and electrons as its corresponding atom in the parent compound. The concept of percompositions was introduced by the chemist Joseph Priestley in 1805, and they have since become a fundamental part of computational chemistry for understanding molecular structures. A percompound is often used to represent a molecule
