Bonded interactions

Definition

Bonded interactions refer to the attractive forces that occur between atoms in a molecule, resulting in the formation of chemical bonds such as covalent, ionic, and metallic bonds. These interactions are crucial for determining the molecular structure, stability, and reactivity of compounds. Understanding these interactions involves analyzing the electronic configurations of atoms and how they influence molecular dynamics and behavior.
