In case we are speaking about the chemical bonding, the latest means the way in which atoms or groups of atoms are connecting (bonded) together. There are different types of chemical bonding: covalent (polar, non-polar, coordination, pi-dative, pi-, sigma-, delta-, electron-deficient etc), ionic, metal bonding, hydrogen bond and Van der Waals. Covalent - a chemical bond formed via the summarizing of the electrons from two different of similar atoms to form the molecular orbitals. Ionic - simply the electrostatic interaction between ionized atoms or molecular ions forming the compound. Metal bonding - quite similar to the ionic bond, while the ionized atoms donate their electrons into the cooperative usage. Hydrogen bond - the type of weak bond formed between the hydrogen atom covalently connected to the other more electronegative atom and the pronounced acceptor of the electrons (often F or O). Van der Waals interaction - the weakest known interatomic or intermolecular type of interactions, which are due to the transient shift of the electron density.
