What is GE on the periodic table?
What is GE on the periodic table?
Germanium (Ge), a chemical element between silicon and tin in Group 14 (IVa) of the periodic table, a silvery-gray metalloid, intermediate in properties between the metals and the nonmetals.
What are two properties that make a metal a good choice to use as a wire?
The ductility of metals (such as copper) is it’s ability to be stretched into wires. A metal’s conductivity (with regards to electrics) is it’s ability to transfer electricity through it. Copper is typically used in home wiring because of it’s relative availableness and it’s good ductility and conductivity.
What are the two properties metals?
Physical Properties of Metals Metals are lustrous, malleable, ductile, good conductors of heat and electricity. Other properties include: State: Metals are solids at room temperature with the exception of mercury, which is liquid at room temperature (Gallium is liquid on hot days).
Is silver more conductive than copper?
The most electrically conductive element is silver, followed by copper and gold. Although it is the best conductor, copper and gold are used more often in electrical applications because copper is less expensive and gold has a much higher corrosion resistance.
What is the example of hardness?
Hardness is a measure of how much a material resists changes in shape. Hard things resist pressure. Some examples of hard materials are diamond, boron carbide, quartz, tempered steel, ice, granite, concrete. Ability of material to resist wear, tear, scratching, abrasion cutting is called hardness.
What do you mean by ductility class 8?
The property which allow the metals to be drawn into wires is called ductility.
Why are bells made of metals Class 8?
bells are made from metals because metals have a property of producing a ringing on striking called sonorous property. metals are also very strong and light.
What is displacement reaction of Class 8?
In displacement reaction a more reactive metal displaces a less reactive metal but a less rwactive metal cannot displace a more reactive metal.
