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.
Group 14 elements such as silicon and germanium are often used as semiconductors due to their properties of being able to conduct electricity under certain conditions. These elements have four valence electrons, allowing them to easily form covalent bonds, which play a crucial role in their semiconductor behavior.

What period on the periodic table of elements contains radioactive elements and what are they called?
The period on the periodic table of elements that contains radioactive elements is the 7th period. These elements are called actinides and include elements such as uranium and plutonium.
Which mineral is a sulfate a compound that contains a -SO4 group?
Gypsum is a common mineral that contains sulfate, which is in the form of the sulfate group (-SO4). The sulfate group is often found in minerals such as anhydrite and barite as well.
A group of related data elements treated as a unit called?
A group of related data elements treated as a unit is called a record. It typically represents a single entity or item and contains fields that store specific attributes or information about that entity. Records are often organized within a database to facilitate efficient data management and retrieval.
A column of elements are called a group or what?
A column of elements in the periodic table is called a group or a family. Groups have similar chemical properties due to their similar electron configurations.
What is the name for the metalloids that are conducters?
Metalloids that can conduct electricity are often referred to as semiconductors. Silicon and germanium are two commonly used semiconductors in electronic devices.
What group number of elements do not often bond?
Elements in group 18 do not often form bonds.
What three elements that are used in semiconductors?
Silicon is the most common element used in semiconductors due to its abundance and well-understood properties. Germanium is another element used in semiconductors, although less commonly than silicon. Arsenic and phosphorus are often incorporated as dopants to introduce either additional electrons (n-type doping) or electron vacancies (p-type doping) in semiconductors.
The most common mineral group contains what kind of minerals?
The most common mineral group is the silicate mineral group, which is characterized by minerals containing silicon and oxygen, often combined with other elements such as aluminum, iron, calcium, or magnesium. Examples of silicate minerals include quartz, feldspar, and mica.
Contains elements with similar properties?
A group or set of elements that have similar physical or chemical properties, such as metals or nonmetals in the periodic table. These elements often exhibit comparable behaviors and characteristics due to their shared electronic configurations or atomic structures.
What period on the periodic table of elements contains radioactive elements and what are they called?
The period on the periodic table of elements that contains radioactive elements is the 7th period. These elements are called actinides and include elements such as uranium and plutonium.
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.
Which mineral is a sulfate a compound that contains a -SO4 group?
Gypsum is a common mineral that contains sulfate, which is in the form of the sulfate group (-SO4). The sulfate group is often found in minerals such as anhydrite and barite as well.

What is the name for the metalloids that are conducters?
Metalloids that can conduct electricity are often referred to as semiconductors. Silicon and germanium are two commonly used semiconductors in electronic devices.
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.
What do elements within a group have a similar number of?
Elements within a group have a similar number of valence electrons. These electrons are responsible for the chemical properties of an element, which is why elements within the same group often have similar chemical behavior.
