Metals have high melting and boiling points compared to non-metals because they are good conductors of heat and electricity, while non-metals are poor conductors of heat and electricity. Metals are solids at room temperature except mercury which is the only metal that is a liquid.Continue Reading
Metals are strong, while non-metals are brittle. Metals produce sound when they are struck, while non-metals do not. Metals are lustrous and shine, while non-metals are dull. Metals have high density compared to non-metals.
Metals such as aluminum, gold and silver are malleable and can be beaten into sheets. Metals such as aluminum and copper are ductile, and they can be pulled into wires. Metals form basic oxides such as magnesium oxide while non-metals form acidic oxides such as sulphur dioxide, sulphur trioxide and carbon dioxide.Learn more about States of Matter
Sodium chloride has a high melting point because of the strong electrostatic attraction between its positive and negative ions; this requires more heat energy to overcome. All ionic compounds have high melting points for this reason.Full Answer >
There is no metal that does not conduct electricity entirely, but there are some metals that are less effective conductors than others. Metal atoms have electrons in their outer shells that are not tied to any particular atom and can flow freely within the metal when electricity is applied.Full Answer >
Metals are good conductors of heat and electricity. Metals are sonorous and produce sound when struck. Metals such as aluminum, copper and iron are malleable and ductile. This means that they can be beaten into sheets and drawn into wires.Full Answer >
Although metals are supposed to be good conductors of electricity and heat, metals like mercury, lead, alloys of iron and chromium, titanium and stainless steel are poor conductors when compared to silver, copper and gold. For example, stainless steel 310 has an electrical conductivity of 1.28 x 10E6 siemens/m, while mercury's electrical conductivity is 1.1 x 10E6 siemens/m. However, silver, which has the highest electrical conductivity of all metals, has a n electrical conductivity of 62.1 x 10E6.Full Answer >
