What is the state of aggregation under normal conditions for silicon?
Aggregate state of silicon
There are various compounds with oxygen of non-metals, which under normal conditions are in a solid state of aggregation. For example, such substances include silicon. The main silicon compounds are silicon oxide (SiO2) and its silicates, which have a complex structure.

Silicon properties and its role
Silicon is a substance that has a gray tint with a gloss. In terms of its structure, silicon is not inferior to the structure of diamond. In each of its crystals, an atom surrounded by a tetrahedral bond with four others has a covalent bond, which is weaker than the carbon atoms in a diamond. In a silicon crystal, under normal conditions, a specific fraction of covalent bonds is destroyed. In this regard, it contains free electrons, which provide electrical conductivity. With such a process as lighting and heating, the number of broken bonds increases, therefore, the number of free electrons and the electrical conductivity itself increase. Silicon is brittle, with a density of approximately 2.33 g / cm3. Silicon has three stable isotopes:
2814Si (92.27%);
2914Si (4.68%);
3014Si (3.05%).
Silicon serves as a semiconductor, namely, a source of energy (solar panels) is produced from it. In the metallurgy industry, silicon steels are obtained from silicon, which have high heat resistance and acid resistance.
