Properties: The melting point of silicon is 1410°C, boiling point is 2355°C, specific gravity is 2.33 (25°C), with a valence of 4. Crystalline silicon has a metallic grayish color. Silicon is relatively inert, but it is attacked by dilute alkali and by halogens. Silicon transmits over 95% of all infrared wavelengths (1.3-6.7 mm).
Uses: Silicon is one of the most widely used elements. Silicon is important to plant and animal life. Diatoms extract silica from water to build their cell walls. Silica is found in plant ashes and in the human skeleton. Silicon is an important ingredient in steel. Silicon carbide is an important abrasive and is used in lasers to produce coherent light at 456.0 nm. Silicon doped with gallium, arsenic, boron, etc. is used to produce transistors, solar cells, rectifiers, and other important solid-state electronic devices. Silicones range from liquids to hard solids and have many useful properties, including use as adhesives, sealants, and insulators. Sand and clay are used to make building materials. Silica is used to make glass, which has many useful mechanical, electrical, optical, and thermal properties.

Why are silicon and oxygen the main elements in the Earth's crust?
To start off, Silicon and oxygen are among the most abundant elements in the universe: oxygen is the third most common element and silicon is the seventh. They readily combine to form silicon dioxide (silica), making it one of the most common solid materials in the universe. Additionally, silica is less dense than many other abundant substances within Earth. Therefore when Earth formed, the more silica-rich materials tended to float toward the surface.

What are the six elements that are not metals but have some properties of metals?
Those are Metalliods, which are Boron, Silicon, Germanium, Arsenic, Antimony, and Tellurium.
What elements have some properties of a metal but some properties of a nonmetal?
These elements are called "metalloids" : boron, silicon, germanium, arsenic, antimony, tellurium, and polonium. They form a diagonal line on the periodic table running down and to the right. Some allotropes of other elements display the properties of metalloids.
