What else can I help you with?
What does germanium do?
Germanium does no "do" anything.
Is germanium a conductor or an insulator?
neither, germanium is a semiconductor
How strong is germanium?
Germanium is a relatively brittle metalloid with a Mohs hardness of about 5.5, making it weaker than many metals like iron or copper. While it exhibits good electrical conductivity and is used in electronics, its mechanical strength is limited, which restricts its use in structural applications. Overall, germanium's strength is adequate for its specific applications but not comparable to that of stronger metals.
Will germanium sink or float in water?
Germanium has a density of about 5.32 g/cm³, which is significantly greater than the density of water (approximately 1 g/cm³). Therefore, germanium will sink when placed in water.
What are two reasons why density is a useful property for identifying substances?
Density is specific for each substance. Also the measurement is generally simple.
How can you get a pure sample of germanium?
Pure germanium is obtained by distllation of germanium tetrachloride, followed by hydrolysis of GeCl4 to GeO2 and reducing of GeO2 with hydrogen to Ge.
What is the specific resistance of pure silicon?
The specific resistance of pure silicon is around 2300 ohm-cm at room temperature.
What are pure semiconductors?
silicon and germanium
Does germanium form a monatomic or diatomic in pure form?
Neither, it is a crystalline solid in pure form.
What does germanium smell like?
Germanium itself does not have a distinct odor. It is a metalloid and is typically odorless in its pure form.
What kind of odor does germanium have?
The pure element has no odor as it is a solid and nonvolatile.
Is gold a better conductor than germanium?
Yes. Pure gold is a much better conductor than pure germanium is.
When a potential is applied to pure germanium in what direction do the electrons and holes move?
in pure germanium there are effectively noconduction band electrons or holes, so they don't move at all.
What is the specific heat of germanium?
The specific heat of germanium is approximately 0.32 J/g°C.
What is the germanium odor?
Germanium does not have a distinct odor. In its pure form, germanium is a hard, grayish-white metalloid. It is commonly used in electronics and optical devices.
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.
What is the natural state of germanium?
Germanium is a metalloid that is commonly found in nature in the form of germanium dioxide (GeO2) or germanite, which is a rare mineral. It is typically found in combination with other elements rather than in its pure form.
