What Is The Valency Of Scandium?

Are you curious to know what is the valency of scandium? You have come to the right place as I am going to tell you everything about the valency of scandium in a very simple explanation. Without further discussion let’s begin to know what is the valency of scandium?

What Is The Valency Of Scandium?

The periodic table, a fundamental tool in chemistry, is a structured arrangement of elements, each with its own unique properties. Scandium, a transition metal, is one such element that has intrigued scientists and chemists for its diverse applications and distinctive properties. In this blog, we’ll explore the valency of scandium and its significance in the world of chemistry.

The Element Scandium

Scandium, represented by the symbol Sc and atomic number 21, is a transition metal found in the d-block of the periodic table. It is named after Scandinavia, the region where it was first discovered in the early 19th century. Scandium is a relatively rare element in Earth’s crust, making up only a small fraction of its composition.

Valency Of Scandium

Valency, in chemistry, refers to the number of bonds an element can form when it reacts with other elements. For scandium, its valency can vary depending on the chemical compounds it forms.

  1. Scandium in Its Elemental Form (Sc): In its pure elemental form, scandium does not readily form compounds. It exists as Sc₂O₃ (scandium oxide) in nature. Its valency in this form is often considered +3, meaning it can form three bonds with other elements when it reacts.
  2. Scandium in Compounds: When scandium combines with other elements, it commonly exhibits a valency of +3. This means it tends to lose three electrons when forming chemical bonds. Scandium’s most stable oxidation state is +3, and it usually forms ionic compounds with other elements.

Significance In Chemistry

Scandium’s valency of +3 plays a crucial role in various chemical applications and industries. Some notable aspects include:

  1. Alloy Production: Scandium is often used as an alloying element in the aerospace and sports equipment industries. When combined with aluminum, it enhances the material’s strength, making it ideal for aircraft and sports equipment like bicycles and baseball bats.
  2. Solid Oxide Fuel Cells: Scandium-stabilized zirconia (ScSZ) is a crucial component in solid oxide fuel cells (SOFCs). These fuel cells efficiently convert chemical energy into electrical energy, providing a clean and sustainable power source.
  3. Lighting and Electronics: Scandium iodide, when doped with various elements, emits intense white light, making it useful in high-intensity discharge lamps and certain electronics applications.
  4. Laser Technology: Scandium-doped aluminum garnets (ScAlGaN) are used as a gain medium in certain solid-state lasers, which are widely used in scientific research and medical applications.


Scandium, with its valency of +3, is a versatile and valuable element in the world of chemistry and industry. Its unique properties and ability to form bonds with other elements make it essential for various applications, from aerospace engineering to fuel cell technology. Understanding scandium’s valency and its role in chemical reactions helps scientists and engineers harness its potential for innovations that benefit society and the environment.


Why Is The Valency Of Scandium 3?

Electronic configuration of Sc is [Ar] 3d1, 4s2. Scandium element for attending stability give 3 electrons from 3d and 4s. So it has +3 oxidation state. So 3d is also considered as valence shell.

Why Is The Valency Of Scandium 2?

For example, Scandium metal’s electrons per shell are 2, 8, 9, 2 and its outer shell has only 2 electrons. Hence, the valence electron count of scandium is 2. d- block elements have 1-10 electrons in the d- shell.

What Is 3 Valency Called?

Therefore, elements with a valency equal to 3 are called trivalent.

What Is 2 Valency Called?

All elements having valency 2 are called divalent . In which group all the elements do not have same number of valence ele… All the elements in a group (family) have a common valency. For exampl…
