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.
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.
The outermost electrons in an atom are called?
Valence electrons
What are the electrons in the outmost shell of an atom called?
the electrons in the outermost shell of an atom are considered to be the valence electrons.
What electrons are involed in bonding?
The valence electrons are involved in chemical bonding.
How many valence electrons in germanium have?
4, like all semiconductors.

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.
Are free electron in valence band or conduction band?
In semiconductors free electrons are in conduction bands.
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.
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
Why does a semiconductor have fewer free electron than a conductor?

What are valence band?
The quantum mechanical energy band where electrons reside in semiconductors that participate in interatomic bonding.
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 is a valence ring?
explain the function of the" "valence ring
Explain how valence electrons in an atom are used to form a full outermost energy level?
The electrons on the outermost energy level of the atom are called valence electrons.
What do carbon silicon and germanium have in common?
They're all group IV 4 valence electrons all semiconductors, thus the base for transistors.
