Why is platinum a good conductor of electricity?

It has one electron in the valence, so it is a good conductor. Platinum, also, has a single valence electron. However, there are 6 electron shells — one more than silver. There are 77 (17+32+18+8+2) electrons shielding the valence electron.

Is platinum a semiconductor or conductor?

Platinum is a conductor. The resistance of a platinum wire is higher that other conductors. As such it can be used as a heater filament.

Which is the non conductor of electricity?

Answer: Examples of non conductors or insulators of electricity – plastic, glass, paper, air, leather etc.

Which metal is non conductor of electricity?

Tungsten and Bismuth are metals which are poor conductors of electricity. There are many, but some include Aluminum, Bismuth, Gallium, Indium, Lead, Thallium, Tin, Ununhexium, Ununpentium, Ununquadium, and Ununtrium.

Is platinum a heat conductor?

Platinum is a good conductor of heat because the particles of it are closely packed to each other in metal lattice. Lead is considered to be the conductor of heat but a poor conductor of heat because it does not allow enough electrons to pass through it easily.

Is platinum an ohmic conductor?

Palladium and platinum are common components in ohmic contact metallisation schemes to III-V semiconductors. Many of the original III-V ohmic contacts were gold-based and although these contacts possess low resistance values, they are plagued by problems of stability and uniformity of interface structures.

What are examples of non conductor?

Solution: Sulphur, Phosphorus, Wood are non-conductors of electricity due to no presence of free electrons in outermost shell.

Which material is not conductor?

Materials that do not let current flow easily are called insulators. Most nonmetal materials such as plastic, wood and rubber are insulators.

What is the best non conductor?

Some examples of non-conductive materials include paper, glass, rubber, porcelain, ceramic and plastic. Of these materials, glass, ceramic and plastic are standard throughout a variety of industries and are often plated with metal to alter their appearance and physical properties.

What are examples of non conductors?

Insulators oppose electrical current and make poor conductors. Some common conductors are copper, aluminum, gold, and silver. Some common insulators are glass, air, plastic, rubber, and wood. Insulators that can be polarized by an electric field are called dielectrics.
