How many times stronger is metal matter than wood?

It cannot be said how many times stronger than wood is the conductivity of metallic substances, because wood does not conduct electricity at all, so there is no comparison.

Metals conduct electricity, while dried wood does not conduct electricity.

Because there are electrons that move freely in metal, but not in wood.

The essence of conducting electricity is the result of the directional movement of freely moving electrons.

Why do metals conduct electricity.

Matter is made up of atoms, and the structure of the atom is composed of the nucleus located in the center of the atom and the electrons outside the nucleus, the nucleus is positively charged, the electrons outside the nucleus are negatively charged, and the electrons outside the nucleus orbit around the nucleus under the constraints of the nucleus. The electrons inside the metal can be free from the shackles of the nucleus, and move freely outside the nucleus, called free electrons, normally, the movement of free electrons is chaotic, when there is an electric current in the circuit, the free electrons will move in the same direction, that is, the formation of directional movement, so that the metal can conduct electricity.

Metals are all electrically conductive, and only conductive electricity knows the strength and weakness of the ability to mark the chain.

Metal is a substance with lustrous (i.e., strong reflection of visible light), malleable, easy to conduct electricity, heat and other properties. The vast majority of metal elements on Earth exist in nature in a chemical state.

This is because most metals are chemically active, and only a very small number of metals such as gold and silver exist in a free state. Metals are widely present in nature and are extremely common in life, and are a very important and most widely used class of substances in modern industry.

Metals are divided into two types: reactive metals and passivation metals. According to the order of metal activity, pre-hydrogen metals are called active metals, and post-hydrogen metals are passivation metals. The metals with the weakest electrical conductivity, i.e., greater resistance, are bismuth or germanium.

Extended Information: Common Metals and Their Uses:

1. Tungsten (W) Among various metal elements, tungsten is the most difficult to melt and the most difficult to volatilize metal element. Tungsten is mainly used in the manufacture of alloy steel; Pure tungsten is mainly used in the manufacture of tungsten wire in lamps, and is also used in electronic instruments, optical instruments, etc.

2. Chromium (CR) Chromium is a silvery-white metal with extremely high hardness and corrosion resistance, which is used for electroplating and manufacturing special steel.

3. Manganese (MN) is pure and brittle, which is difficult to be applied in production and life, but the alloy of manganese has a wide range of uses. Manganese steel is both hard and tough, making it an ideal material for making rails, bearings, and armor plates.

4. Lithium (Li) Lithium is the lightest metal element with the largest specific heat. Lithium is not only used in the manufacture of ultra-light alloys and lithium batteries, but is also an important material for cutting-edge technologies. Lithium alloy can greatly reduce weight and energy consumption in the aerospace industry, and play an important role in the atomic energy industry.

5. Titanium (Ti) The specific strength of titanium (the ratio of strength to specific gravity) is the highest among all metal elements. Titanium and titanium alloys are new structural materials, hard and light, mainly used in the manufacture of aircraft, submarines, corrosion-resistant chemical equipment and various mechanical parts. Titanium alloy can maintain high strength in the temperature range of -253 500 °C, which is an ideal aerospace material.

The electrical conductivity of metals is generally relatively strong; Silicon and germanium, which are between metals and non-metals, are semiconductor materials.

When the historical resistance of the substance becomes zero, the conductivity is extremely strong, which belongs to the phenomenon of superconductivity.

So the answer is: strong, semiconductor, superconducting

The use of semiconductor materials with conductivity worse than metals and stronger than non-metals can be made into electronic components such as diodes and transistors; Scientists have discovered that the resistance of certain substances becomes zero at very low temperatures, which is the phenomenon of superconductivity: the use of superconducting materials can reduce electrical energy losses when it comes to generating, transmitting, and storing electricity

So the answer is: semiconductors, zero, electrical energy

Depends on the resistivity of the metal material.

Or conductivity.

Definition of conductor resistivity: =e je is the magnitude of the applied electric field, j is the magnitude of the current density, and the si unit of resistivity is ohms.

m (·m or ohmm). Conductivity: =1 definition) The greater the conductivity, the stronger the conductivity, and vice versa.

At the same time, the resistivity of the metal By assuming that the conduction electrons in the metal move as freely as the molecules of the gas, the expression for the resistivity of the metal can be derived: =m (e 2 n ) where n is the number of free electrons per unit volume, and is the average time between two consecutive collisions between the electrons and the metal atoms. That is, the conductivity of the metal also depends on the amount of lead conducted.

Hope it helps

The strength of a metal's ability to conduct electricity depends on the resistivity of the metal material.

It seems to be a cross-sectional area, length, temperature.
