Non-metals do not react with water (or steam) to evolve Hydrogen gas. Non-metals do not react with dilute acids. 4. Reaction of Metal and Non-metal: Many metals form ionic bonds when they react with non-metals. Compounds so formed are known as Ionic Compounds.
Most metals react with oxygen to form compounds known as oxides. Rust is the name given to the oxide of iron and, sometimes, the oxides of other metals. The process by which rusting occurs is also known as corrosion. Corrosion is very much like coustion, except that it occurs much more slowly.
