#REDIRECT [[Hydrogen bond]]
In the study of [[Chemistry]], a '''hydrogen bond''' is said to occur between [[Hydrogen]] and either [[Nitrogen]], [[Oxygen]], or [[Fluorine]] when the two [[atoms]] come in to close proximity and are held at a reasonably unchanging (and close in [[Molecule|molecular]] terms) distance by intra- or inter-molecular electromagnetic forces. 
 
Hydrogen is the most abundant [[element]] in the [[universe]].  It is also the most common component of [[Organic chemistry|organic molecules]] and so hydrogen ''bonding'' has significant influence on every basic component of all known [[Life|living mater]] including but by no means limited to: [[Liquids|liquid]] [[water]], [[protein]]s, and [[nucleic acids]].
 
The electromagnetic forces that manifest as hydrogen bonding (really, ''all'' [[chemical bonding]]) are believed to arise from the motions of the individual [[subatomic particles]] "inside" the respective atoms and molecules themselves.  Mathematical descriptions or models, even of simple two-particle "closed" systems of inter-reacting (dynamically moving) charged particles, require complex [[Electrodynamics|electrodynamic]] calculations using [[Methods of triple integration in 3 and 4 dimensional elliptical coordinate space|some reasonably advanced calculus]] to fully describe the relevant fields.  Methods of accurate computer modeling for the electron densities of complex molecules and reactions (like in the cases of proteins and nucleic acids) have proven quite challenging.
