Why is Copper a good conductor and how is it's structure different from silicon and germanium?
The reason why copper is a good conductor is because there are a lot of free electrons that can carry the flowing current efficiently. These free electrons do not remain permanently associated with the copper atoms, instead they form an electron ‘cloud’ around the outside of the atom and are free to move through the solid quickly. http://web1.caryacademy.org/chemistry/rushin/StudentProjects/ElementWebSites/copper/uses_of_copper.htm
Which of the following would be classified as a metalloid A aluminum B copper C tin D silicon?
Silicon.
What metaloid elements are in period 4?
There is not one but there are two metalloids in Period 4 of the periodic table. They are germanium and arsenic. There is a link below to the Wikipedia post on the metalloids so you can have a look at them.
What is aluminum alloy 226?
It is a casting alloy with Silicon and Copper similar to CA 313
What is the scientific name of copper?
The scientific name of copper is 'Copper'. It has the chemical symbol 'Cu'. 'Cu'. is from Latin and means 'Cuprum. 'Cuprum is also the Latin name for 'Cyprus', which is where copper was first mined/found, by the ancients.
What are some examples of metalloid elements?
7 metalloids:BoronArsenicAntimonyTelluriumPoloniumSiliconGermanium

When a piece of copper and another of germanium are cooled from room temperature to 800 K then the resistance?
Each of them increases
What does copper sulfate have in it?
copper silicon and oxygen.
Why germanium is not suitable for rectification?
Any semiconductor can be used for rectification, so germanium is suitable.However what you may be thinking of is power rectifiers. Germanium cannot operate with a junction temperature above about 60C, so this is a significant limitation on the power handling capability of germanium power rectifiers (even copper oxide or selenium power rectifiers can handle more power, so they were used for many years before quality silicon power rectifiers became available).
What is basic material for making a transistor?
It is the middle portion of the transistor
Which of the following would be classified as a metalloid aluminum or copper or tin or silicon?
Silicon is a metalloid.
What elements from the periodic table make sterling silver?
silver, copper. copper can be replaced by germanium, zinc, platinum
What element is made into computer chips?
Silicon is the typical base material , aluminum or copper are the interconnect metals.
Which is a better conductor of electricity copper or silicon?
Silicon is only a semiconductor. Copper on the other hand is used to make wires and is an excellent conductor of electricity.
How do scientists collect germanium?
Scientists collect Germanium from certain types of mineral specimens. These include Sphalerite and other ores from silver, copper, and lead.
