What is a property of germanium?
Pure germanium is a hard, lustrous, gray-white, brittle metalloid. It has a diamondlike crystalline structure and it is similar in chemical and physical properties to silicon. Germanium is stable in air and water, and is unaffected by alkalis and acids, except nitric acid.
What are 5 physical properties of silicon?
The Physical properties of Silicon are the characteristics that can be observed without changing the substance into another substance. Physical properties are usually those that can be observed using our senses such as color, luster, freezing point, boiling point, melting point, density, hardness and odor.
Is germanium brittle or malleable?
The element is brittle rather than ductile; the atoms in its crystals are arranged as are the carbon atoms in diamond. The electrical and semiconducting characteristics of germanium are comparable to those of silicon.
What are some physical properties of silicon?
Physical Properties of Silicon The atomic number of silicon is 14 and its relative atomic mass is 28.085 u. The density of silicon is 2.3296 gram per cubic centimeter. The silicon melting point is 1,410°C and the silicon boiling point is 3,265°C. Silicon in its purest form is an intrinsic semiconductor.
What are 5 physical properties of carbon?
The Physical properties of Carbon are the characteristics that can be observed without changing the substance into another substance. Physical properties are usually those that can be observed using our senses such as color, luster, freezing point, boiling point, melting point, density, hardness and odor.
