What group contains elements that are often used as semiconductors?

For a pure semiconductor:
The requirement for a semiconductor is that there is a small energy gap between electrons in their ground state and in an excited "band" of energy levels. A material is considered a semiconductor when the energy gap is approximately equal to the boltzmann constant multiplied by the temperature. (kT)
Therefore it is difficult to say a general rule as to what group would give semiconductors as this would take a much more in depth analysis of the energy levels. For example, in group 14, silicon is a well known semiconductor, however Germanium is verging on semi metal, and tin and lead are clearly metals.

A column of elements are called a group or what?
A group is often called a chemical family.
The properties of elements in a in the periodic table are often similar?
Elements in the same group have same number of valence electrons and hence have similar chemical and physical properties.
What is group 11 on the periodic table?
Well the question is a little confusing. So I am giving the two possible answers. The eleventh element is sodium. The elements in the eleventh group are copper, silver, gold and roentginum
What period on the periodic table of elements contains radioactive elements and what are they called?
it was found in 1896. you can not find them on the periodic table. you may find some, but often some are.
What element has both metallic and nonmetallic properties?
We generally refer to these elements as semiconductors. There is something akin to a "diagonal line of elements" in the periodic table that separates the metals from the nonmetals. Elements on the left of this diagonal are metals, and elements on the right are nonmetals. The elements that make up this diagonal are boron, silicon, germanium, arsenic, antimony, tellurium, polonium, and astatine, and they have both metallic and nonmetallic properties. awesome mean something good.
What group number of elements do not often bond?
Elements in group 18 do not often form bonds.
A column of elements are called a group or what?
A group is often called a chemical family.
What are the elements to combine to form a color that used in LEDs?
Lots of compounds have been used in LEDs Many of these are based on III-V semiconductors using elements from group 13 and 15, such as gallium nitride, indium phosphide, gallium arsenide and "mixed" nitrides InGaN The simple compounds produce light of a particular wavelength, often coatings of phosphors are used to produce extra colors.
What is a group often used for electrodes or catalysts because they do not combine easily with other elements called?
The platinum group is often used for electrodes or catalyts because they do not combine easily with other elements.
The properties of elements in a in the periodic table are often similar?
Elements in the same group have same number of valence electrons and hence have similar chemical and physical properties.
What is group 11 on the periodic table?

What period on the periodic table of elements contains radioactive elements and what are they called?
it was found in 1896. you can not find them on the periodic table. you may find some, but often some are.
What 5 other elements do organic compounds often contain?
Carbon, Hydrogen, Oxygen, Nitrogen, Phosphorous, Sulfur and then Hemoglobin contains Iron and Chlorophyll contains magnesium.
Which group of elements are commonly a variety of color compounds?
The transition metals often produce colorful compounds.
What element has both metallic and nonmetallic properties?
We generally refer to these elements as semiconductors. There is something akin to a "diagonal line of elements" in the periodic table that separates the metals from the nonmetals. Elements on the left of this diagonal are metals, and elements on the right are nonmetals. The elements that make up this diagonal are boron, silicon, germanium, arsenic, antimony, tellurium, polonium, and astatine, and they have both metallic and nonmetallic properties. awesome mean something good.
What do you by the family of an element?
On the periodic table, the elements fall into groups (the vertical columns) which are often called families. The reason is that elements in a group are chemically similar to each other.
What element is often used as semiconductors for computer?
Semiconductors are 90% of the time made of Silicon, enhanced into P-Type or N-Type depending on needed polarities. P = Positive, N = Negative, Boron gas has excess negative electrons and is used in doping to create N-Type Silicon.
