The Versatile Element: Silicon’s Crucial Role in Technology and Construction

Silicon: The Versatile Chemical Element

Silicon is a chemical element that is widely used in various fields of industry and technology. It is a non-metal, with the symbol Si, and has an atomic number of 14.

Silicon is the second-most abundant element in the earths crust, making up almost 28% of its weight. This article will explore the properties of silicon and its crucial role in digital age technologies and construction.

Physical properties of Silicon

Silicon is a dark blue-grey, lustrous, and hard solid that is brittle in nature. It crystallizes with a diamond structure, making it a semiconductor material with excellent thermal conductivity.

It has a boiling point of 2630C and a melting point of 1414C. Silicon has the unique feature, which makes it important in the manufacturing industry as its resistance to high temperatures makes it ideal for different applications.

Chemical properties of Silicon

Silicon is an inert element that doesn’t react with acids, bases, or most of the other elements or compounds. However, it reacts with halides and metals to form alloys.

The most common way silicon reacts is with oxygen, forming a thin layer of SiO2, also known as silicon dioxide, which serves as a passivating barrier in preventing further reaction. Additionally, with carbon, silicon forms silicon carbide, a hard and strong ceramic material used for different applications, including as an abrasive.

Uses of Silicon in the Digital Age

Silicon has found extensive use in the digital age; it is an essential component of most electronic devices. In the form of doped silicon, it is used in transistors, a tiny switch that controls the flow of electricity in electronic devices.

In addition, silicon is used in diodes that permit electricity to flow in only one direction, and also in liquid crystal displays (LCDs), which are used to make thin and lightweight screens that are found in most televisions, laptops, and cellphones. Integrated circuitry that characterizes modern computer architecture cannot be possible without silicon.

Integrated circuits (ICs) are made using a doping technique, whereby impurities are introduced into a silicon wafer to alter its electrical properties. The most common doping elements include phosphorus and boron, which creates “n” and “p” type silicon, forming the fundamental building blocks of digital integrated circuits.

Uses of Silicon in construction and glassware

Silicon is widely used in construction, mainly in the form of silica or quartz, which is found abundantly in the earth’s crust. The use of silica as a raw material for the production of cement, ceramics, and glassware is well known.

The glass-forming properties of silica, when combined with other oxides such as calcium and magnesium, make it possible to produce glass of different colors, transparency, and chemical resistance. In construction, strong and durable concrete is obtained by adding finely-ground silica to the mix.

Silicon has also found use as an insulator in a variety of electronic devices as it can help prevent the flow of electricity. This makes it an essential component of devices such as microwaves, and many other appliances.


In conclusion, silicon is a versatile element in its applications across various fields. Its unique set of physical and chemical properties, as well as its abundance in the earth’s crust, make it an essential element in modern technology, construction, and manufacturing.

Although we might not always think about it, silicon has become an integral part of our daily lives, making our world what it is today. From phones and televisions to construction, silicon plays an important role in the world we live in.

3) Electronic Configuration of Silicon

Understanding electron structure

The concept of electron structure and the arrangement of electrons is based on the work of the Danish physicist Niels Bohr. He proposed that atoms have different orbits like planets orbiting the sun.

Each orbit can hold a specific number of electrons known as its electron capacity.

Electron distribution in Silicon

Silicon has an atomic number of 14, which means it has 14 electrons. The electrons are distributed among different shells, with the first shell able to accommodate two electrons and the second shell able to accommodate up to eight electrons.

In the case of silicon, we have two electrons in the first shell, eight electrons in the second shell, and four electrons in the third shell. This gives us the electronic configuration of 2,8,4.

Orbital sub-energy levels

The electronic configuration of an element is determined by the azimuthal quantum number, which determines the sub-energy levels of the orbitals. These sub-energy levels have different shapes and orientations depending on the value of the quantum number.

The lowest sub-energy levels are filled first, followed by the higher levels, in a process known as the Aufbau principle.

Arrangement of electron configuration

The electron configuration of an element can be represented in a shorthand notation. Orbital boxes are used to represent each sub-energy level as a box, and its electrons are represented as arrows, which depict the spin of the electrons.

In the case of silicon, we represent each shell as a box, and we draw two arrows in the first shell, eight arrows in the second shell, and four arrows in the third shell. The arrangement of the electrons in silicon’s outermost shell determines its chemical properties.

The four valence electrons of silicon make it a semi-conductor, which has properties between that of an insulator and a conductor. This makes it an important material in electronic devices.



In conclusion, understanding the electronic configuration of an element is crucial for understanding its properties and its behavior in chemical reactions. Silicon’s electronic configuration of 2,8,4 reflects its unique properties and its role in the digital world.

The arrangement of the electrons in its outermost shell makes it a semi-conductor with a wide range of applications in electronic devices. In summary, this article explored the properties and importance of silicon, an essential component in modern technology, construction, and manufacturing.

Silicon’s unique set of physical and chemical properties, such as being a semiconductor material with excellent thermal conductivity, enable its use in various fields, including the digital age, glassware, and construction. The electronic configuration of silicon, represented in shorthand notation, determines its properties and behavior in chemical reactions, making it crucial to understand its arrangement.
