What are the physical properties and uses of sulfur?
Pure sulfur is a tasteless, odourless, brittle solid that is pale yellow in colour, a poor conductor of electricity, and insoluble in water. It reacts with all metals except gold and platinum, forming sulfides; it also forms compounds with several nonmetallic elements.
What are the 3 chemical properties of metals?
Chemical Properties of Metals
- The density of metals is usually high.
- Metals are malleable and ductile.
- Metals form an alloy with other metals or non – metals.
- Some metals react with air and corrode.
- Metals are good conductors of heat and electricity.
- Generally, metals are in a solid state at room temperature.
What are the properties and uses of metals?
Properties of Metals
- Luster: Metals are shiny when cut, scratched, or polished.
- Malleability: Metals are strong but malleable, which means that they can be easily bent or shaped.
- Conductivity: Metals are excellent conductors of electricity and heat.
What are the most common properties of metals?
Properties of Metals
- Metals have relatively high melting points. This explains why all metals except for mercury are solids at room temperature.
- Most metals are good conductors of heat.
- Metals are generally shiny.
- The majority of metals are ductile.
- Metals tend to be malleable.
What properties do all metals share?
Metals conduct electricity, are ductile, malleable and have a “metallic” luster.
What is the physical property of metal?
Physical properties
| Metals | Non-metals |

| Good conductors of electricity | Poor conductors of electricity |
| Good conductors of heat | Poor conductors of heat |
| High density | Low density |
| Malleable and ductile | Brittle |
Is nickel a good conductor of electricity?
This extremely useful metal is No. 28 in the periodic table of the elements, between the elements cobalt and copper. Nickel is a fairly good conductor of electricity and heat and is one of only four elements (cobalt, iron, nickel and gadolinium) that are ferromagnetic (magnetized easily) at room temperature.
Which of the following is the best conductor of electricity?
Copper
Why is silver the best conductor of electricity?
The most electrically conductive element is silver, followed by copper and gold. Silver is the best conductor because its electrons are freer to move than those of the other elements, thereby making it more suitable for the conduction of electricity and heat than any other element.
Why silver is not used in wires?
Though silver is a very good conductor of electricity but still that is not used in electric wiring primarily due to its cost. It’s very expensive compared to the widely used wiring material copper. Another reason for not using silver is that , it oxidizes easily and tarnishes when it comes in contact with air.
Why are silver and copper good conductors?
The most electrically conductive element is silver, followed by copper and gold. As to why silver is the best conductor, the answer is that its electrons are freer to move than those of the other elements. This has to do with its valence and crystal structure. Most metals conduct electricity.
Which metal is the best conductor of heat silver or copper?
1 Answer. Silver is the best conductor of both heat & electricity among metals with a thermal conduction value of about 430 W/(mK). ❖ Gold & copper both come respectably close to silver. ❖ Silver also has the highest thermal conductivity of any element & the highest light reflectance.
Which is the best conductor of heat silver or copper?
Copper is a good conductor of heat. This means that if you heat one end of a piece of copper, the other end will quickly reach the same temperature. Most metals are pretty good conductors; however, apart from silver, copper is the best.
Is Silver best conductor of heat and electricity?
Silver is an excellent conductor of heat, while stainless steel is a poor conductor. In fact, silver is twice as good a conductor as aluminum, and nearly 10 times as good as a conductor as low-carbon steel. Copper and gold are the only metals that come close to silver in thermal conductivity.
