Sodium and magnesium oxides are alkaline. Aluminium oxides are amphoteric (reacting both as a base or acid). Silicon, phosphorus, sulfur, and chlorine oxides are acidic. Some non-metal oxides, such as nitrous oxide (N2O) and carbon monoxide (CO), do not display any acid/base characteristics.
A solid is characterized by structural rigidity and resistance to a force applied to the surface a solid object does not flow to take on the shape of its container nor does it expand to fill the entire available volume like I gas
