What properties of the materials used in computer chips make them useful as switches that turn on and off?
The silicon is a semiconductor and can be doped to control its conductivity and create the junctions needed to make diodes and transistors. These diodes and transistors can act as switches and logic gates in properly designed circuits. Silicon can also be easily oxidized to become a robust waterproof insulator to passivate and protect the circuits and components beneath it.
The aluminium and/or copper are just good conductors used to "wire" the silicon components together and provide pads that can be used to attach wires or metal beads so that the chip can be connected to external circuits.

What property of the materials used in the computer chips makes them useful as switches that turn electricity on and off?
Computer chips, lasers and many other modern electronic devices are made by etching circuits into microscopically etc
How are properties useful in classifying material?
Constituents, appearance, shape, and taste are used to classifying materials. This is useful because materials with similar properties can be placed in the same category.
What property of the materials used in computer chips makes them useful as switches that turn electric current on and off?
They are semiconductors and their electrical properties can be very precisely controlled by adding dopant impurities to create a wide variety of components integrated into one chip. Transistors of various types created by this doping process can act as switches or amplifiers depending on the other components integrated around them and connected to them.
What properties makes certain metalloids useful as switches to turn electric current on and off?
any property
How are properties useful in classifying materials in chemistry?
Properties are useful in classifying materials in chemistry because they provide information about a substance's behavior, composition, and structure. By analyzing properties such as physical appearance, chemical reactivity, and conductivity, chemists can categorize materials based on similarities and differences, allowing for a better understanding of their characteristics and potential uses.
When is it useful not useful to heat materials?
It is useful to heat materials when attempting to change their physical properties, such as melting or shaping. However, it may not be useful to heat materials that are sensitive to heat and may degrade or become damaged, or when temperature control is crucial for the material's stability.
What properties of semiconductors make them useful in electric devices?
They can be used as a base material for computer chips
Why is viscosity useful?
Technology design involve a knowledge of the flowing properties of materials. Viscosity is dependent on temperature and pressure.
What property makes semimetals useful as switches to turn a small elecric current on the off?
The property that makes semi-metals useful as "switches" is that their varying ability to conduct electricity.
How is nanotechnology related to materials science?
Nanotechnology is about material, but in material science you work with any scale of them. if you decrease size of material's particle to nanometer, then you can find some useful properties. nanotechnology is working with materials in nanoscale.
What property makes semi-metals useful as switches to turn a small electric current on and off?
The property that makes semi metals useful as "switches" is that their varying ability to conduct electricity.
When are series circuits useful-?
