Bismuth is a chemical element with the symbol Bi and atomic number 83. It is a dense, silvery-white metal with a pinkish tint. Bismuth is a relatively rare element, accounting for only about 0.00002% of the earth’s crust. It is used in a variety of applications, including cosmetics, pigments, and pharmaceuticals. But what group does bismuth belong to?

The Periodic Table

To understand what group bismuth belongs to, we first need to look at the periodic table. The periodic table is a tabular arrangement of the chemical elements, ordered by their atomic number, electron configurations, and chemical properties. The elements are organized into rows and columns, based on their electron configurations.

Bismuth’s Electron Configuration

Bismuth has an electron configuration of [Xe] 4f14 5d10 6s2 6p3. This means that it has six valence electrons in its outermost shell. Valence electrons are the electrons in the outermost shell of an atom that participate in chemical reactions.

Bismuth’s Group

Based on its electron configuration, bismuth belongs to group 15 of the periodic table. Group 15 is also known as the nitrogen group or pnictogens. The elements in this group have five valence electrons, which makes them highly reactive.

Properties of Group 15 Elements

Now that we know what group bismuth belongs to, let’s take a closer look at the properties of group 15 elements.

Physical Properties

The elements in group 15 have a wide range of physical properties. Nitrogen is a colorless, odorless gas at room temperature, while bismuth is a dense, silvery-white metal. The other elements in the group, phosphorus, arsenic, antimony, and moscovium, are all solids at room temperature.

Chemical Properties

Group 15 elements are highly reactive due to their five valence electrons. They tend to form covalent compounds, and many of them are important components of biological molecules. For example, nitrogen is a key component of amino acids, while phosphorus is a component of DNA and RNA.

Uses of Bismuth

Bismuth has a number of uses, including:


Bismuth oxychloride is used in cosmetics as a pigment and to improve the texture of products like eyeshadow and foundation.


Bismuth subsalicylate is used to treat stomach ulcers and other gastrointestinal problems.

Other Uses

Bismuth is also used in alloys, as a substitute for lead in some applications, and in some types of fire sprinklers.


In conclusion, bismuth belongs to group 15 of the periodic table, also known as the nitrogen group or pnictogens. Group 15 elements are highly reactive due to their five valence electrons, and bismuth has a number of important applications in cosmetics, pharmaceuticals, and other industries.
