Relatively speaking, semiconductors have more free electrons than insulators but fewer than conductors. For example, silicon is a semiconductor, the intrinsic carrier concentration is about 1 x 1010 cm-3, at room temperature. A proxy for the electron concentration is resistivity. Comparison at room temperature below:
aluminum (metal); resistivity ~ 2.7 x10-8 [Ω-m]
silicon: > 130 [Ω-m], depending on purity
insulator: > 1 x 1010 [Ω-m]

What else can I help you with?
Are there free electrons in the air?
THeres too many
Why can conductors conduct electricity?
Conductors, like metals, have many free electrons that are able to move easily through the material. When an electric field is applied, these free electrons can flow, allowing the conductor to conduct electricity.
Is a 2p a conductor or an insulator?
A 2p orbital does not determine whether a material is a conductor or insulator. Conductivity is determined by the number of free electrons that can move through a material. Materials with many free electrons are typically conductors, while materials with few free electrons are insulators.
Materials with many free electrons are considered what?
Materials with many free electrons are considered good conductors of electricity. These materials allow the flow of electrical current easily due to the presence of numerous free electrons that can move freely within the material. Examples include metals like copper and aluminum.
Are the free moving electrons in metals account for many of the properties of metals?
Yes, the free-moving electrons in metals are responsible for many of their properties. These electrons allow metals to conduct electricity and heat, be malleable and ductile, and exhibit luster. The delocalized nature of these electrons also contributes to metals being good conductors of electricity and heat.
How many valence electrons in germanium have?
4, like all semiconductors.
How many electrons does promethium contain?
The neutral atom of promethium contain 61 electrons.
Good conductors contain many free?
Oh, dude, good conductors contain many free electrons. It's like having a bunch of tiny, super chill partygoers just bouncing around, carrying all the electric current for the rest of the material. So, yeah, free electrons are the life of the conductivity party in materials like metals.
A plasma must contain many what?
