How many types of metal are there?

Do you know how many different metals are there?

At present, there are 108 kinds of elements and 90 kinds of metal elements, which occupy a relatively large position.

These 90 metal elements also include three semi metals, namely boron, silicon and arsenic.

However, there are so many kinds of metals that it would take a lot of time to understand everything.

Therefore, there are two methods to classify these metals.

The United States, Britain and Japan divide the metals into ferrous metals and non-ferrous metals.

The former Soviet Union and other Eastern European countries divided metals into black metals and colored metals.

This method of distinguishing metals by color is used in China.

However, there is not much scientific basis for this method.

Therefore, on this basis, people further divide metals into heavy metals, light metals, precious metals and rare metals according to their properties and uses.

Heavy metals are mainly metals with a density of more than 4.5 g/cm3, while light metals have a density of less than 4.5 g/cm3.

FAQs about types of metals

What is metal?

Metal is a kind of material with luster (i.e. strong reflection of visible light), ductility, easy conductivity and heat conduction.

The vast majority of metal elements on the earth exist in nature in a combined state.

This is because the chemical properties of most metals are more active, and only a few metals such as gold and silver exist in free state.

What types of metal are magnetic?

Magnetic metals include iron, nickel, cobalt, steel, stainless steel and rare earth metals. Some of these materials are always magnetic. However, some materials, such as stainless steel, do not exhibit magnetism unless they contain a specific chemical composition.

Iron

Iron is the strongest ferromagnetic metal. It is they that endow the earth with magnetism and form an important part of the core.

Nickel

Nickel is also a common magnetic metal with ferromagnetic properties. Nickel has always been used to make coins.

Cobalt

Cobalt is a ferromagnetic metal. In the past 100 years, cobalt has been widely used because of its excellent magnetic properties.

Cobalt can be used to make soft and hard magnets.

Steel

Steel also exhibits ferromagnetism due to its iron content. In most cases, steel is attracted by magnets. Therefore, steel can also be used to make permanent magnets.

Stainless steel

Some stainless steels are magnetic, others are not. Alloy steel becomes stainless steel by adding chromium to the alloy. The composition and molecular structure of ferritic and martensitic stainless steels lead to their magnetism.

Different nickel content is the main cause of magnetic difference.

Rare earth metals

In addition to the magnetic elements mentioned above, some rare earth compounds also have magnetic properties. Gadolinium, samarium and neodymium are magnetic rare earth metals.

Magnets with different properties can be manufactured by combining the above metals with iron, nickel and cobalt.

What types of metal are not magnetic?

Only a few metals in the periodic table are magnetic, while most other common metals are non-magnetic, such as aluminum, gold, silver, copper and so on.

Aluminium

The crystal structure of aluminum is the same as that of lithium and magnesium, making it non-magnetic. All three materials are paramagnetic metals.

Gold

Like most metals, gold is an diamagnetic metal. All diamagnetic metals, including gold, have a weak magnetic attraction to pure magnets.

Silver

Silver is another non-magnetic metal. The diamagnetism of silver makes it nonmagnetic.

Copper

Copper itself is not magnetic, but it interacts with magnets in some way (e.g. eddy currents).

Power plants use this property of copper to generate electricity.

What are the heavy metals?

Heavy metals include mercury, lead, cadmium, gold, silver, copper and iron.

Heavy metals refer to metals with a density greater than 4.5g/cm3.

Heavy metals are very difficult to be biodegraded.

On the contrary, they can be enriched hundreds of times under the biological amplification of the food chain and finally enter the human body.

Some heavy metals enter the human body through food, interfere with the normal physiological function of the human body, and endanger human health. They are called toxic heavy metals.

In terms of environmental pollution, heavy metals mainly refer to heavy elements with significant biological toxicity such as mercury, cadmium, lead, chromium and metalloid arsenic.

Heavy metals can interact strongly with proteins and enzymes in the human body, making them inactive, and may also accumulate in some organs of the human body, causing chronic poisoning.

What is the most precious metal in the world?

The most precious metal in the world is plutonium, which costs US $113400 per ounce.

Plutonium is a kind of radioactive metal, which is used to alloy fuel pellets for nuclear power stations and explosive materials for nuclear weapons.

Why is plutonium so expensive?

In nature, plutonium exists only in trace amounts in uranium ore. The largest source of plutonium comes from uranium irradiated in nuclear reactors.

As a by-product of the nuclear power industry, only about 20 tons of plutonium are produced each year.

Since this highly radioactive metal has no use other than nuclear energy or nuclear weapons (and some limited uses in scientific research, it is lethal to human beings if not handled properly), it is highly regulated, difficult to obtain and extremely expensive.
