Which lists the elements in order from least conductive to most conductive?

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?

Boron Family

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?

Table of semiconductor materials

Group Elem. Band gap (eV)
VI 1 2.05
VI 1 0.33
III-V 2 6.36
III-V 2 5.96

What is the largest semiconductor chip maker?

Intel Corporation

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.

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 element is most likely to carry electric current easily?

tin

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 is the property of nonmetals to evaporate easily?

They are also poor conductors of electricity for they tend to form negative ions by gaining or sharing electrons [to be stable] unlike the metals. Hence, they have high ionization energy and high electronegativity values. In addition, nonmetals are usually volatile, which means that they evaporate easily.

Which metal is most likely to form a positively charged ion?

Nickel (Ni)

What are the important changes in electronic devices?

The correct answer is electronic devices have become smaller. Explanation: The metalloids refer to the substance or the elements that possess characteristics of both non-metals and metals

Which is the best conclusion about particles A and B?

Which is the best conclusion about Particles A and B? Particle A orbits the nucleus, and Particle B is located in the nucleus. An atomic physicist determines that an atom is composed of 8 positively charged particles and has a mass of 15 amu.

What has very little mass?

The neutron helps keep the nucleus together. The electron has a negative charge and very little mass (1800 times less than protons and neutrons). Table 1. Relative masses and charges of the particles in an atom.

Can iodine bend without breaking?

cobalt (co). carbon (c), iodine (i), and si (si) are non-metal elements. a particular characteristic of non-metals is that they are brittle when they are in the solid form. then they will break instead of bending

Which group of elements would be used for electrical wires?

Metals

Which group is least likely to form bonds?

Answer. Noble gases are a unique set of elements in the periodic table because they don’t naturally bond with other elements. group 18

Which substance is most likely the most dense?

Silver

Which elements are most likely to form a covalent bond?

The chemical elements most likely to form covalent bonds are those that share electrons, such as carbon, as opposed to those that take them from another element to form an ionic bond. In general, they are nonmetals with similar electronegativities.

Which element does not form a covalent bond?

A covalent bond is formed by the sharing of electrons by two non-metals. The elements that is unlikely for form covalent bond are K and Ar

Can every atom form covalent bonds?

Covalent bonds are usually found in atoms that have at least two, and usually less than seven, electrons in their outermost energy shell, but this is NOT a hard and fast rule. Hydrogen, for example, is a unique atom that bears closer examination.

What is the smallest particle of a covalent compound?

The force of attraction between the shared electrons and the positive nuclei of both atoms holds the atoms together in the molecule. A molecule is the smallest particle of a covalent compound that still has the properties of the compound

Is ci2 a compound or element?

Chlorine is in group 17 of periodic table, also called the halogens, and is not found as the element in nature – only as a compound. The most common of these being salt, or sodium chloride, and the potassium compounds sylvite (or potassium chloride) and carnallite (potassium magnesium chloride hexahydrate).

What’s the smallest particle of a compound?
