Is germanium A insulator?
Is germanium a conductor or an insulator? Answer: germenium is a semi conductor. it exist in a sort of limbo between conductors and insulators .
Is silicon and germanium an insulating material?
A semiconductor material has an electrical conductivity value falling between that of a conductor, such as metallic copper, and an insulator, such as glass. Some examples of semiconductors are silicon, germanium, gallium arsenide, and elements near the so-called “metalloid staircase” on the periodic table.
What is a good insulator of electricity?
Plastic, wood, glass and rubber are good electrical insulators. That is why they are used to cover materials that carry electricity. The plastic covering that surrounds wires is an electrical insulator.
Which metal is an insulator of electricity?
In a conductor, electric current can flow freely, in an insulator it cannot. Metals such as copper typify conductors, while most non-metallic solids are said to be good insulators, having extremely high resistance to the flow of charge through them.
Which metal is the best insulator?
As you can see, out of the more common metals, copper and aluminum have the highest thermal conductivity while steel and bronze have the lowest.
What are 10 insulators?
10 Electrical Insulators
- Rubber.
- Glass.
- Pure water.
- Oil.
- Air.
- Diamond.
- Dry wood.
- Dry cotton.
What are 4 examples of insulators?
Examples of insulators include plastics, Styrofoam, paper, rubber, glass and dry air.
Is platinum a good insulator?
Platinum is an element with high electrical conductivity and is more ductile than gold, silver, or copper. It is less malleable than gold. The metal has excellent resistance to corrosion, is stable at high temperatures, and has stable electrical properties.
Is platinum better than gold for electronics?
In the industrial world, gold is used primarily as connectors in electronic devices, such as cell phones and computers, because it’s corrosion and tarnish resistant, conducts electricity well, and disperses heat quickly. Platinum is stronger and more durable than gold.
Does platinum react?
Platinum is chemically inert and will not oxidize in air at any temperature. It is resistant to acids and is not attacked by any single mineral acid but dissolves readily in aqua regia. The metal is rapidly attacked by fused alkali oxides and by peroxides and will react with fluorine and, at red heat, with chlorine.
What are 3 interesting facts about platinum?
Facts About Platinum
- Atomic number (number of protons in the nucleus): 78.
- Atomic symbol (on the periodic table of elements): Pt.
- Atomic weight (average mass of the atom): 195.1.
- Density: 12.4 ounces per cubic inch (21.45 grams per cubic cm)
- Phase at room temperature: solid.
Why is Platinum better than gold?
The main reason for this is that precious metals are priced by weight, and platinum is much denser than gold, meaning it will be heavier. Another reason why platinum rings are more valuable than gold is because the metal is much rarer.
