Ions in their gas-like state are highly reactive and will rapidly interact with ions of opposite charge to give neutral molecules or ionic salts. Ions are also produced in the liquid or solid state when salts interact with solvents (for example, water) to produce solvated ions, which are more stable, for reasons involving a combination of energy and entropy changes as the ions move away from each o… WebA hydrogen ion is created when a hydrogen atom loses or gains an electron.A positively charged hydrogen ion (or proton) can readily combine with other particles and therefore is only seen isolated when it is in a …
