Silicon compounds are chemical substances that contain silicon, a versatile element found in group 14 of the periodic table. These compounds can form various structures, including silicates, silicones, and silicon dioxide. They are widely used in industries such as electronics, construction, and agriculture due to their unique properties. Silicon dioxide, commonly known as quartz, is one of the most abundant silicon compounds and is found in sand and glass. Silicones, which are synthetic compounds made of silicon, oxygen, carbon, and hydrogen, are used in products like sealants, lubricants, and medical devices.
