One common method to obtain pure samples of selenium is through the process of sublimation. Selenium can be heated to a temperature where it vaporizes and then allowed to condense back into a solid state in a clean container, resulting in a relatively pure sample. Further purification techniques such as recrystallization or distillation may also be employed to increase the purity of the sample.
Selenium is a pure chemical element.
Yes, selenium is odorless in its pure form. When selenium compounds are formed and interact with other substances, they may produce odors.
Samples that are pure water include distilled water, rainwater, and water that has been filtered through a reverse osmosis system. These samples do not contain any dissolved minerals or impurities.
No, selenium is a chemical element found on the periodic table with the atomic number 34 and symbol Se. It is a non-metal element that can exist in various forms, such as pure elemental selenium or in compounds with other elements.

Pure plutonium is obtained as a result of the reaction of PuF4 with calcium, barium or lithium.
Yes, selenium is odorless in its pure form. When selenium compounds are formed and interact with other substances, they may produce odors.
Selenium is a chemical element. It can be said to be a pure substance; there is nothing else found in it.
The most straightforward way to make a pure sample of calcium is to electrolyze a molten calcium salt with an "inert" cathode such as platinum. Considerable care is required to prevent reaction of pure calcium with the ambient atmosphere.
Samples that are pure water include distilled water, rainwater, and water that has been filtered through a reverse osmosis system. These samples do not contain any dissolved minerals or impurities.
No, selenium is a chemical element found on the periodic table with the atomic number 34 and symbol Se. It is a non-metal element that can exist in various forms, such as pure elemental selenium or in compounds with other elements.
You can buy pure element samples from reputable online suppliers such as Luciteria or GalliumSource. These suppliers offer a wide range of pure element samples for educational and collection purposes. Be sure to verify the credibility of the supplier before making a purchase.
Selenium dioxide, SeO2
Selenium was first utilized in 1817 by the Swedish chemist Jöns Jakob Berzelius. He discovered this element while he was investigating sulfur samples from a sulfuric acid production plant.
