How many valence electrons does metalloids have?
Metalloids typically have 3 to 6 valence electrons. This intermediate number of valence electrons allows metalloids to exhibit both metal and non-metal characteristics.
Do metalloids have a full valence shell of electrons?
No, metalloids typically do not have a full valence shell of electrons. They have properties that are in between metals and nonmetals, which means they can exhibit characteristics of both types of elements.
What is a group of elements with few valence electrons that conduct heat amd electricity?
halogen NOTE added by Dr.J.): A halogen doesn't have a few valence electrons. They have 7 valence electrons.
What type of bonding happens to metalloids and metals and why?
• Metalloids: usually form covalent bonds with atoms of metals, nonmetals and other metalloids. They can easily take electrons from metals and lose electrons to nonmetals. • Metalloids: usually form covalent bonds with atoms of metals, nonmetals and other metalloids. They can easily take electrons from metals and lose electrons to nonmetals. They form because they want their valence shell to be full. Metals usually lose valence electrons because they want to stabilize their valence shell. Metalloids depends because they have different properties of metals and non metals.
Under what conditions will metalloids conduct heat and electricity?
Metalloids can conduct heat and electricity under conditions where they have partially filled valence electrons. This allows them to exhibit some metallic properties. However, metalloids are not as efficient conductors as metals nor as insulators as nonmetals.
How many valence electrons does metalloids have?
Metalloids typically have 3 to 6 valence electrons. This intermediate number of valence electrons allows metalloids to exhibit both metal and non-metal characteristics.
How many valence electrons in germanium have?
4, like all semiconductors.
Do metalloids have a full valence shell of electrons?
No, metalloids typically do not have a full valence shell of electrons. They have properties that are in between metals and nonmetals, which means they can exhibit characteristics of both types of elements.
Why does a semiconductor have fewer electrons than a conductor?
Valence electrons only are able to cross the energy gap in semiconductors since it is greater than that of conductors. That is why semiconductors have fewer free electrons than conductors.

halogen NOTE added by Dr.J.): A halogen doesn't have a few valence electrons. They have 7 valence electrons.
Are free electron in valence band or conduction band?
In semiconductors free electrons are in conduction bands.
Why is silicone a widely preferred semiconductor?
because its valence electrons are free and it is used to the free moving of electrons..so they are used as semiconductors

What are valence band?
The quantum mechanical energy band where electrons reside in semiconductors that participate in interatomic bonding.

Valence electrons only are able to cross the energy gap in semiconductors since it is greater than that of conductors. That is why semiconductors have fewer free electrons than conductors.
How many valence shell electrons are there in semiconductor atoms?
Silicon, the most widely used semiconductor, has four valence electrons. This places it in between the conductive metals, which have one to three valence electrons, and the non-conductive non-metals which have five to eight valence electrons.
What are three examples from the periodic table to explain valence electrons and dot diagrams?
Valence electrons are the electrons on the outer circle of the Bohr Diagram of the element.Dot diagrams are the same as Bohr Diagrams.BOHR/DOT DIAGRAM:VALENCE ELECTRONS:
