Silicon is a solid at room temperature. It is a metalloid, which means it has properties that are intermediate between metals and nonmetals. In its pure crystalline form, silicon has a shiny, metallic luster and is hard and brittle.
At higher temperatures, silicon can melt into a liquid state, and at even higher temperatures, it can vaporize into a gas. However, these transformations typically occur at significantly elevated temperatures: silicon melts at around 1,414 degrees Celsius (2,577 degrees Fahrenheit) and boils at approximately 2,355 degrees Celsius (4,271 degrees Fahrenheit).
In summary, under normal conditions, silicon is found in its solid state, and its unique physical and chemical properties make it an essential material in electronics and semiconductor industries.
