How did the element selenium get its name?

Selenium was called after Selene, the Greek goddess of the moon. Despite the fact that the element mercury is named after the planet Mercury, it is not named after the planet. They were both named after the Roman god of the same name. The original elements were silver and sulfur.

Although it was first discovered in 1803, it wasn't until five years later that it was successfully isolated by a French scientist named Berthollet. He used a process called "carbonization" to create a solid form of selenium that could be seen under the microscope. Carbonized cotton threads were also used as a fiber source. Today, silicon-based materials are used instead.

In 1897, German chemist Carl Vogel announced that he had synthesized elemental selenium using an electric spark. However, some scientists believe that Berthollet may have done so first because his work on carbonizing fabrics was known about before Vogel's announcement. Even though Berthollet didn't actually produce selenium itself, he did develop several methods for preparing other elements. One of these methods was actually used by Vogel to prepare his sample of selenium.

The next major contribution to the study of selenium came from Thomas Edison. In 1902, he invented the incandescent lamp which uses electricity to heat a thin wire to a red hot temperature.

Why is the symbol for selenium se?

Because the element is chemically discovered with tellurium, the name stems from the Greek Selene, who was the Greek goddess of the Moon (Tellus was the Roman goddess of the Earth). In 1817, the Swedish scientist Jons Jacob Berzelius discovered selenium while attempting to separate tellurium from an impure sample. He called the new substance "Selenia", which became the name for the entire series of 21 elements.

In honor of this achievement, Berzelius proposed the naming of the elements after Greek and Roman gods or heroes. The proposal was accepted by the meeting of the French Academy of Sciences in 1829, and thus the names selenium and berzelium were adopted. However, because berzelium is a feminine noun, it was necessary to represent the element with a male sign; sulfur was chosen instead.

The actual symbol for selenium was proposed by English chemist John Webster Young in 1872. He suggested using the Greek letter Σ for selenium since its appearance is similar to that of sulfur. The first occurrence of this symbol in print was in Young's article "On some New Elements Found in Coal" published in the London Journal of Science in December 1872. Young also used the symbol in his book On the Composition of Matter published two years later.

Young's proposal was followed by other scientists. In 1875, German chemist Carl Vogel proposed the use of the Latin letter S for selenium.

How did selenite get its name?

Selenite was called after Selene, the Greek goddess of the Moon, and literally means "Moon stone" (not to be confused with albite-orthoclase feldspar moonstone). The name references to the stone's moon-like faint reflection. In addition, it is said that when struck with a hammer, it sounds like silver.

There are three types of selenite: white, blue, and gray. All contain small amounts of iron, magnesium, calcium, and other elements. The color of selenite varies depending on the amount of iron present in the rock. When the concentration of iron is high, it can be red; if there is more magnesium than iron, then the selenite will be green; if there is more calcium than iron, then the rock will be brownish yellow; if there is no dominant element, then it is considered white.

In nature, selenite usually forms as large crystals that often grow within meteorite impacts sites. However, small granules can form by precipitation from volcanic ash or soil debris. Some specimens have been found embedded in rock layers formed by ancient seas. These fossils show that selenite was once part of a coral reef environment.

The first documented occurrence of selenite was in 1725, when German miners discovered it in their Saxony region mines. It was soon after named for its resemblance to the moon!

How is selenium related to sulfur and tellurium?

Selenium is a chemical element with the atomic number 34 and the symbol Se. It is a nonmetal (rarely regarded a metalloid) with qualities halfway between sulfur and tellurium in the periodic table, as well as similarities to arsenic. Its name comes from the Greek word for "silver" or "golden." Selenium is a grayish-white solid that readily oxidizes in air to a reddish-brown powder. The elemental form of selenium is known as selenium itself, but it also exists in minerals such as glaucous gold, glazed gold, rhodesite, and pyrochlore.

Like sulfur, which it resembles chemically, selenium occurs in two forms: selenium(IV), or selene(+4), and selenium(II), or selenate(-2). Selenium(0) is a zero-valent state of matter; however, pure selenium is always in its highest oxidation state, so it never occurs in nature in this form. Elemental selenium can be found in minerals such as glaucous gold, glazed gold, rhodesite, and pyrochlore.

Tellurium has similar properties to sulfur but is more reactive. It can exist in four different oxidation states: +4, 0, -3, and -5.

How did Mercury get its name?

Mercury is named after the gods' messenger. The Roman Mercury wore a helmet with wings and wore shoes with wings. Mercury travels fast around the sun. That's how it acquired its moniker. The Hebrew word for mercury is mim, which is also the word for mirror.

Mirrors have many uses; they allow us to look at ourselves properly, see things we might miss otherwise, and find hidden flaws. Mercury is used in mirrors because it softens other elements in the glass and allows them to be worked on with more ease. Before mercury was used in mirrors, only clear or colored glass could be polished.

Polishing glasses is a time-consuming process; only high-quality optics from the 16th century on were polished because glass that was going to be viewed from close up didn't need to be transparent. Polished glass appears shiny because of the reflection of light from its surface.

In 1789, William Hyde Wollaston invented the first practical mercury bath gas lamp. It was an improvement on Simon Kewin's earlier design, which used antimony instead of mercury. In 1816, John Ericsson built the first iron-framed boat using these lamps as fuel for its boilers. The ship was called the "U.S.G.L." (United States Glass-Lamp).

What is the element mercury named after?

Mercury, named after a Roman deity associated with speed and agility, is a chemical element that has captivated mankind for thousands of years. Mercury is the only metallic element that is liquid under normal circumstances. It is also the smallest planet in the solar system by mass.

The idea of linking qualities to elements first arose in ancient Greece. The Greeks believed that each human being was composed of four elemental substances: earth, air, fire, and water. These elements could be combined in different proportions to create any substance we know today. For example, iron is an alloy of copper and zinc with some oxygen added; it can't be made solely from these three elements.

In Chinese medicine, mercury is used to treat problems related to the brain, heart, lungs, kidneys, and large blood vessels. It is also thought to relieve pain, especially chronic pain, and enhance cognitive function. In contrast, European medicine views mercury as toxic to the nervous system.

In chemistry, mercury is the most common name for elemental mercury, Hg. This colorless or slightly gray metal is soft, malleable, and ductile. It is reactive with oxygen and other chemicals it comes into contact with. Elemental mercury is obtained commercially by amalgamation of gold, silver, platinum, or copper with chlorine gas followed by treatment with sodium hydroxide solution to remove impurities.
