Silicon is a chemical element with the symbol Si and atomic number 14. It is a hard, brittle crystalline solid with a blue-grey metallic lustre, and is a tetravalent metalloid and semiconductor. It is a member of group 14 in the periodic table: carbon is above it; and germanium, tin, and lead are below it. It is relatively unreactive. Because of its high chemical affinity for oxygen, it was not until 1823 that Jöns Jakob Berzelius was able to prepare it in pure form. Its melting and boiling points of 1414 °C and 3265 °C respectively are the second-highest among all the metalloids and nonmetals, being only surpassed by boron. Silicon is the eighth most common element in the universe by mass, but very rarely occurs as the pure element in the Earth’s crust. It is most widely distributed in dusts, sands, planetoids, and planets as various forms of silicon dioxide (silica) or silicates. More than 90% of the Earth’s crust is composed of silicate minerals, making silicon the second most abundant element in the Earth’s crust (about 28% by mass) after oxygen.

The discovery and early use of silicon in Britain can be traced back to the early 19th century. In 1823, Jöns Jakob Berzelius was able to prepare silicon in pure form for the first time. However, it wasn’t until the late 19th century that silicon started to be used in various industries in Britain.
One notable British scientist involved in silicon research and development was Sir William Crookes. He conducted extensive research on silicon and its properties, and his work laid the foundation for further advancements in silicon technology.
In the early 20th century, companies in Britain started to recognize the potential of silicon and began using it in various applications. One such company was the British Electrical and Allied Industries Research Association (BEAIRA), which was established in 1920. BEAIRA conducted research on silicon and its applications in electrical engineering, leading to the development of new technologies and products.
The Role of Silicon in Modern Technology
Silicon plays a crucial role in modern technology, particularly in the field of electronics. It is used extensively in the production of semiconductors, which are the building blocks of electronic devices such as computers, smartphones, and televisions.
Semiconductors made from silicon are able to control the flow of electrical current, making them essential for the operation of electronic devices. Silicon-based transistors, for example, are used to amplify and switch electronic signals in computers and other electronic devices.
Silicon is also used in the production of solar panels, which convert sunlight into electricity. Solar panels are made up of silicon cells that absorb photons from sunlight and generate an electric current. This renewable energy source has become increasingly important as the world seeks to reduce its reliance on fossil fuels.
