What Is Silicon Vs Silicone?

Introduction

Silicon and Silicone are two substances that sound similar and are often confused with each other. However, they are completely different chemically and functionally. In this article, we will delve deeper into the characteristics of both substances, their properties, applications, and the similarities and differences between them.

What is Silicon?

Silicon is a chemical element. It is the second most abundant element in the earth''s crust, after oxygen. Silicon is a metalloid and has the atomic number 14. It is a gray crystalline solid that has some metallic luster and is a semiconductor. Silicon has several allotropic forms, including amorphous, crystalline, and single-crystal silicon. In its purest form, silicon is a hard, brittle, and crystalline solid with a bluish-gray metallic appearance.

Properties of Silicon

Silicon has several interesting properties, which make it versatile and useful in various applications. Some of these properties include:

- Conductivity: Silicon has semiconductor properties and is a poor conductor of electricity in its pure form. However, when impurities are added to it, it can become a good conductor.

- Melting and boiling points: Silicon has a high melting point of 1,414°C and a boiling point of 3,265°C.

- Chemical reactivity: Silicon is relatively unreactive, and it forms a thin layer of silicon dioxide when exposed to air, which protects it from further reactions.

- Abundance: Silicon is the second most abundant element in the earth''s crust, after oxygen.

- Biological significance: Although silicon is not considered an essential element for life, it has been found to be beneficial for the growth of certain plants.

Applications of Silicon

Due to its unique properties, Silicon finds applications in various fields. Some of these applications include:
