Which lists the elements in order from least conductive to most conductive?
Answer. Answer: Nitrogen (N), antimony (Sb), bismuth (Bi) is the order from least conductive to most conductive.
Which properties are characteristic of metalloids?
Metalloids usually look like metals but behave largely like nonmetals. Physically, they are shiny, brittle solids with intermediate to relatively good electrical conductivity and the electronic band structure of a semimetal or semiconductor.
Which lists the elements in order from most conductive to least conductive potassium?
Answer. Explanation: most conductive – potassium (K). least conductive- germanium(Ge).
Which of the following elements are metalloids check all that apply?
A metalloid is an element that displays properties of both metals and non metals. The metalloids in this list include boron, silicon and tellurium. Tin, aluminium, tungsten and bismuth are metals.
Can metals form basic compounds?
Metals with high oxidation states form oxides whose bonds have a more covalent nature. Ionic metal oxides react with water to give hydroxides (compounds containing the OH− ion) and resultant basic solutions, whereas most nonmetal oxides react with water to form acids and resultant acidic solutions (see the table).
Which metalloid has three valence electrons?
Is germanium a semiconductor?
It is a lustrous, hard-brittle, grayish-white metalloid in the carbon group, chemically similar to its group neighbors silicon and tin. Pure germanium is a semiconductor with an appearance similar to elemental silicon. Elemental germanium is used as a semiconductor in transistors and various other electronic devices.
What is the condition of n-type and p-type semiconductor?
In an n-type semiconductor, the donor energy level is close to the conduction band and away from the valence band. In the p-type semiconductor, the acceptor energy level is close to the valence band and away from the conduction band.
What is Semiconductor give example?
A semiconductor material has an electrical conductivity value falling between that of a conductor, such as metallic copper, and an insulator, such as glass. Some examples of semiconductors are silicon, germanium, gallium arsenide, and elements near the so-called “metalloid staircase” on the periodic table.
What are the two types of semiconductors?
Two main types of semiconductors are n-type and p-type semiconductors. (i) n-type semiconductors. Silicon and germanium (Group 14) have very low electrical conductivity in the pure state.
Which is the most commonly used semiconductor and why?
Why silicon is the most commonly used semiconductor?
- Silicon has much smaller leakage current than that of germanium.
- Silicon can be worked at a higher temperature as compared to germanium.
How many semiconductors are there?

Is Diamond a semiconductor?
Diamond is a wide-bandgap semiconductor (Egap = 5.47 eV) with tremendous potential as an electronic device material in both active devices, such as high-frequency field-effect transistors (FETs) and high-power switches, and passive devices, such as Schottky diodes.
