What are metals and metalloids?

The chemical elements in the periodic table are divided into several categories, including metals, metalloids, and nonmetals. Metals are elements that are good conductors of electricity and heat, have high melting and boiling points, and have a characteristic shine when polished. Metalloids, also known as semimetals, have properties that fall between those of metals and non-metals.

Properties of metals

Metals are solid at room temperature, except for mercury, which is liquid. They have a high density, are malleable and ductile and have a characteristic metallic shine. Metals are also good conductors of electricity and heat, making them useful for electronics and heating products.

Examples of metals

• Iron
• Copper
• Aluminum
• Silver
• Gold

Properties of metalloids

Metalloids have characteristics that are between metals and non-metals. Some of the properties they share with metals include their thermal and electrical conductivity and their ability to form alloys. They are also brittle and brittle like non-metals and do not have the characteristic metallic luster.

Examples of metalloids

• Boron
• Silicon
• Arsenic
• Antimony
• Germanium

Why is it important to know the difference between metals and metalloids?

Knowledge of the properties of metals and metalloids is important in several fields, such as engineering, electronics manufacturing, and medicine. For example, metals are used in the manufacture of automobiles, airplanes, and machinery, while metalloids are used in the production of solar panels and semiconductors for computers.

In conclusion, although metals and metalloids share some properties, such as their ability to conduct electricity, they are different in many ways. While metals are solid at room temperature, have a high melting and boiling point, and are malleable and ductile, metalloids have properties intermediate between metals and nonmetals, making them useful in specific applications.
