Van der Waals Bond Definition
Definition: A van der Waals bond is a secondary interatomic bond between adjacent molecular dipoles. A van der Waals bond may be permanent or induced. Hydrogen Bond Definition - Chemistry Glossary Definition of Hydrogen Bond Definition: A hydrogen bond is a type of attractive (dipole-dipole) interaction between an electronegative atom and a hydrogen atom bonded to another electronegative atom. This bond always involves a hydrogen atom. Hydrogen bonds can occur between molecules or within parts of a single molecule. A hydrogen bond tends to be stronger than van der Waals forces, but weaker than covalent bonds or ionic bonds. This is a basic diagram of an atom, with protons, neutrons and electrons labeled. Atom Definition: An atom is the defining structure of an element, which cannot be broken by any chemical means. A typical atom consists of a nucleus of protons and neutrons with electrons circling this nucleus. Atom Examples: hydrogen, carbon-14, zinc, cesium, Cl- (a substance can...
