Answers
Answer:
1).Metals shows the property of malleability while non-metals are non-malleable. Metals are generally those substances that have a shiny surface and thus are lustrous. Whereas non-metals have non-shiny appearance and thus falls under the category of non-lustrous substances.
2).Corrosion is a natural process that converts a refined metal into a more chemically stable form such as oxide, hydroxide, or sulfide. It is the gradual destruction of materials (usually a metal) by chemical and/or electrochemical reaction with their environment.
3).Metal Type. One simple way to prevent corrosion is to use a corrosion resistant metal such as aluminum or stainless steel. ...
Protective Coatings. The application of a paint coating is a cost-effective way of preventing corrosion. ...
Environmental Measures. ...
Sacrificial Coatings. ...
Corrosion Inhibitors. ...
Design Modification.
4).They are usually in the form of a solid at room temperature. They are very good conductors of electricity and heat. Metals are malleable and ductile. They mostly have a very high melting point.
