Similarly copper (I) chloride can be produced as a white precipitate (reaction described below). The metals like copper,silver and gold are so un reactive that they react with water or even steam. The reactivity of the metal determines which reactions the metal participates in. For example, the oxygen atom in water behaves like it has a 2- charge while the hydrogen atoms behave like they have 1+ charges.
