Provide an example of a telluride and a selenide.

A telluride is a compound containing tellurium and a selenide is a compound containing selenium.

Tellurides and selenides are both types of binary compounds, meaning they are made up of two elements. Tellurides contain tellurium and another element, while selenides contain selenium and another element. Both tellurium and selenium are in the same group on the periodic table, known as the chalcogens, which are known for their ability to form compounds with metals.

An example of a telluride is cadmium telluride (CdTe), which is a semiconductor used in solar cells and other electronic devices. It is formed by combining cadmium and tellurium in a 1:1 ratio. Another example is bismuth telluride (Bi2Te3), which is a thermoelectric material used for cooling and power generation.

An example of a selenide is zinc selenide (ZnSe), which is also a semiconductor used in various electronic applications. It is formed by combining zinc and selenium in a 1:1 ratio. Another example is copper selenide (Cu2Se), which is a compound used in photovoltaic cells and other electronic devices.

Overall, tellurides and selenides are important compounds in various industries, particularly in electronics and energy production. Their unique properties make them useful for a range of applications, and ongoing research is exploring new ways to use these compounds in the future.
