The hydrogen bond-an attraction between a hydrogen atom in one molecule and an atom belonging to another molecule-plays a crucial role in determining the characteristics of water and the microscopic structure of ice.
Theorists have predicted that a sufficiently high pressure can alter the bonding in ice, transforming the material from a molecular solid in which hydrogen bonds hold water molecules in place into an ionic material made up of oxygen and hydrogen ions (protons). In this transformation, the strong, covalent bonds that normally link two hydrogen atoms to a single oxygen atom in a ...
