Hydrogen atoms are close together. The electron from each atom feels the attraction from the proton in the nucleus of the other atom. This attraction pulls the atoms together and the electrons are ...

Other hydrogen bonds may temporarily impede proper folding. For example, a protein may get hung up in a repeating loop that involves one or more hydrogen bonds forming, breaking and forming again ...

Each atom then has a complete outer shell of electrons. The slideshow shows how a covalent bond forms between a hydrogen atom and a chlorine atom, making hydrogen chloride. A simple molecule ...

The design and synthesis of supramolecular systems invokes interactions beyond the covalent bond, using, for example, hydrogen bonding, metal coordination and π interactions to bring discrete ...
