Of all the metals, bismuth is one of the most common in our day to day, although we do not know it. Being one of the least toxic for us, it is not surprising that it is used in various fields. But do you really know what this element is? And what are the properties of bismuth?
In this post we will explain what exactly this metal is and what are its uses and properties. In addition, we will give information about where we can find this element in everyday life. Keep reading if you want to know more about the properties of bismuth!
What is bismuth and its uses?
Before discussing the properties of bismuth, let's first clarify what it is. It's a heavy, silvery-white metal with a pinkish sheen that was discovered by Claude François Geoffrey in 1753. It is found naturally on Earth in small quantities. especially in minerals such as bismutite and bismuthine. However, it is relatively rare to find it. Furthermore, bismuth is a chemical element with the symbol Bi and atomic number 83 in the periodic table.
As for the uses of this metal, there are several in the industry and include the manufacture of alloys with other metals such as iron, copper and tin. It is also used in the production of cosmetics, pigments, medicines, and other chemicals. One of the most interesting properties of bismuth is that it is slightly toxic to bacteria, but not to humans, making it a popular ingredient in some personal hygiene products and medicines.

In addition to its practical applications, bismuth also has some interesting properties in the realm of science and technology. For example, this metal has very low electrical conductivity and high infrared reflectivity, which makes it useful in some optical and electronic devices. It is also known for its ability to form crystals with fascinating geometric patterns, which have been used in jewelry and other decorative objects.
Where is bismuth found in everyday life?
Considering the wide variety of uses that bismuth has, it is not surprising that we find it in various products of daily life. Below we will list a few applications of this element:
- Medication: It is present in some medicines such as bismuth subsalicylate, which is used to treat diarrhea and stomach ulcers.
- Cosmetics: Bismuth is found in some cosmetics such as eye shadow, face powder, and lipstick.
- Pigments: It is also used in the production of pigments for paints, inks, and plastics, as it is resistant to fading and corrosion.
- Alloys: Another use that is given to bismuth is in the production of alloys with other metals such as iron, copper and tin. In this way it is possible to improve its mechanical properties.
- Welds: Bismuth is used in some solder alloys because it has a low melting point and is easy to work with.
- Electronics devices: Another application of bismuth is in some electronic devices, such as integrated circuits, switches, and sensors. This is due to its ability to resist corrosion and oxidation.
- Decorative crystals: Finally, it remains to highlight its ability to form crystals with geometric patterns, very popular in jewelry.
What are the properties of bismuth?
Now that we know what this metal is, let's see what are the properties of bismuth. The main features of this element are the following:
- Valencia: 3 and 5
- Atomic number: 83
- Oxidation state: +3
- Atomic mass: 208,980 g / mol
- Density: 9,8 g / ml
- Boiling point: 1560ºC
- Melting point: 271,3ºC
- Electronic configuration: 4f14 5d10 6s2 6p3
Besides, bismuth has more properties to highlight. For example, at standard temperature and pressure, bismuth is in a solid state, either in its pure form or as part of some minerals. Besides, It has more volume in the solid state than in the liquid state. just like water.
It should also be noted that bismuth is a monatomic molecule. What does this mean? Well, it means that a single atom is composed. In addition, it has a total of 41 unstable isotopes to span from the 184Bi al 224Bi. However, there is one that does turn out to be stable, since its half-life is estimated to be more than a billion times the age of the universe. It is the isotope 209Bi. It should be said that bismuth has the highest atomic mass and atomic number of all those elements that are not radioactive. Regarding the half-life of this metal, scientists speculate that it is about 20 trillion years. Therefore it is not surprising that It is surely the last element to disintegrate in the entire universe.
