Silicon is not a metal, though it shares many of the properties of metals. It is called a metalloid. This makes it have many characteristics of metals AND nonmetals. Silicon is a shiny, gray element that conducts electricity like a metal, but also nonmetallic in many ways, such as being brittle.
As also previously indicated, silicon is not a metal. It is a non-metal element, as it lacks many of the typical characteristics of a metal. Non-metals are dull, can’t be beaten into sheets and are poor conductors of electricity. Silicon belongs here because it does not display all of the characteristics of a metal.
You should know silicon is a metalloid. Metalloids are elements that share characteristics of both metals and non-metals. You will find them on the periodic table as in-betweeners! Silicon is a member of this group because it can carry a charge like a metal but has some non-metal properties, including brittleness.
Although silicon is not a metal, it does have many characteristics of a metal. For instance, silicon can carry an electric current, something that is characteristic of metals. This is what makes silicon a good choice for many electronic devices and other objects that require conductivity.
Silicon is not referred to as a metal because it does not exhibit all of the characteristics of a true metal. And though it shares some of the traits of metals, you know, conductive, it lacks important qualities of metals, like being malleable or stretchable. Silicon is also more brittle than a metal, so that's one reason it isn't referred to as a metal.
