Copper is a metal and does not exhibit semiconducting properties like germanium and silicon. Germanium and silicon are semiconductors with a crystalline structure that allows for controlled conduction of electricity. This difference in atomic structure is what gives rise to their unique electrical properties.
What else can I help you with?
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
Does germanium react with metals?
Yes, germanium can react with certain metals to form germanides. These reactions typically occur at high temperatures and under specific conditions. Germanium is capable of forming alloys with some metals, such as with copper to create germanium-copper alloys.
What elements does germanium react with?
Germanium can react with elements such as oxygen to form germanium dioxide, sulfur to form germanium sulfide, and halogens like chlorine to form various germanium halides. It can also form alloys with metals such as tin, copper, and silver.
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.
Which of the following would be classified as a metalloid A aluminum B copper C tin D silicon?
Silicon is classified as a metalloid.

What are some examples of metalloid elements?
Some examples of metalloid elements include silicon, arsenic, boron, and germanium. These elements have properties that are between metals and nonmetals, such as being semi-conductive and having varying degrees of metallic and non-metallic behavior.
If a certain voltage is applied to a copper wire and to a germanium wire of the same thickness and length how will the current in the two wires compare?
The current in the copper wire will be higher than the current in the germanium wire. This is because copper has lower resistance compared to germanium, allowing more current to flow for a given voltage. Germanium has higher resistance due to its crystal structure, which hinders current flow.
Is germanium a good conductor of electricity?
Germanium is a semiconductor, which means its conductivity falls between that of a conductor and an insulator. It is not as good a conductor as metals like copper, but it can conduct electricity under certain conditions.
What happens when silicon reacts with copper chloride?
When silicon reacts with copper chloride, silicon will displace copper from the copper chloride solution to form silicon chloride and copper. The reaction can be represented as: 3CuCl2 + 2Si -> 2SiCl4 + 3Cu
What does copper sulfate have in it?
copper silicon and oxygen.

What Materials that have positive temperature coefficient?
Some materials with a positive temperature coefficient of resistance include silicon, germanium, and thermistors made of certain metal oxides like manganese, cobalt, and copper. These materials exhibit an increase in resistance with an increase in temperature, making them useful in temperature-sensing applications.
When a piece of copper and another of germanium are cooled from room temperature to 800 K then the resistance?
The resistance of the copper piece will increase, while the resistance of the germanium piece will decrease as they are both cooled from room temperature to 800 K. This is because the resistivity of metals like copper generally increases with decreasing temperature, while for semiconductors like germanium, the resistivity decreases with decreasing temperature.
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 elements from the periodic table make sterling silver?
silver, copper. copper can be replaced by germanium, zinc, platinum
