Potassium was discovered in 1807 by Humphry Davy, who derived it from caustic potash (KOH).
It is reasonable to think that at that time he worked in London at the Royal Institution, though he might have lived in his hometown of Penzance, Cornwall
[I've digged that out of the following incomplete citations from en.wikipedia]
- "Davy wrote to Davies Giddy on March 8, 1801 about the offers made by Banks and Thompson, a possible move to London and the promise of funding for Davy's work in galvanism."
- "By June 1802, after just over a year at the Institution and at the age of 23, Davy was nominated to full lecturer at the Royal Institution of Great Britain. In November 1804 Davy became a Fellow of the Royal Society, over which he would later preside"

Who invented potasium?
Potassium is a naturally occurring element, which means that unlike "man made" or synthetic elements, it does not require inventing. Potassium was discovered by British scientist Sir Humphry Davy in the early 1800's. The process that created natural occurring elements like potassium, silicon, oxygen, etc. occurred billions of years ago. After the big bang, the event that formed our universe, small atoms like hydrogen and helium were the only elements in the universe. However, the creation of the first stars created an environment which was hot enough to cause nucleosynthesis: the process of creating heavier elements from smaller ones. As older stars died, they released new/heavier elements into the universe. These new/larger elements were then integrated into new stars, where they were made into even larger elements. This process continued for generation after generation of stars until the present. We currently know of 92 naturally occurring elements. This means that all of the naturally occurring elements on earth, including Potassium, actually come from stars. hope this helps :D
Who is the first scientist who discover a bulb?
Thomas Edison is credited with inventing the first commercially practical incandescent light bulb in 1879. However, Sir Humphry Davy created the first electric light in 1802 by passing an electric current through a platinum filament.
How Joseph Henri moissan discovered the fluorine?
Type your anseName: Fluorine Type: Halogen Density @ 293 K: 0.001696 g/cm3 Discovery of Fluorine In 1530 Georgius Agricola described the use of the mineral fluorspar in metal refining. Fluorspar (which we now know is mainly calcium fluoride) was very useful because it combined with the unwanted parts of metal ores, allowing the pure metal to flow and be collected. Fluorine had not yet been discovered and the 'fluor' in fluorspar came from the Latin word 'fluere', meaning to flow, because this is what it allowed metals to do. The element name fluorine ultimately came from the 'fluor' in fluorspar. Several chemists carried out experiments on fluorspar in the early 1800s including Gay Lussac, Louis Jacques Thenard, Humphry Davy, Carl Wilhelm Scheele and Joseph Priestley. Often they produced what they called fluoric acid - now named hydrofluoric acid - a highly reactive and potentially deadly acid. Even small splashes of this acid on skin can be fatal. Several early attempts to isolate fluorine led to blindings and fatalities. Humphrey Davy wrote: "[fluoric acid] is a very active substance, and must be examined with great caution. In 1809 Andre-Marie Ampere proposed that fluoric acid was a compound of hydrogen and an unknown element. He exchanged letters with Humphry Davy and in 1813 Davy announced the discovery of the new element fluorine, giving it the name suggested to him by Ampere. Davy wrote: "... it appears reasonable to conclude that there exists in the fluoric compounds a peculiar substance, possessed of strong attractions for metallic bodies and hydrogen... it may be denominated fluorine, a name suggested to me by M. Ampere." Fluorine was finally isolated in 1886 by Henri Moissan - whose own work was interrupted four times by serious poisoning caused by the element he was pursuing. Moissan isolated fluorine by electrolysis of dry potassium hydrogen fluoride and anhydrous hydrofluoric acid. To limit corrosion, he built a platinum container and the electrolytic solution was cooled to -23 oF (-31 oC.) The stoppers were made out of fluorite (a more modern name for our old friend fluorspar, which we began this section with). Fluorine was produced at the positive electrode. Henri Moissan received the 1906 Nobel Prize in Chemistry for his achievement.
Where did aluminum get its name?
Name Origin: From the Latin word alumen, meaning a substance having an astringent or bitter tasteNamed by Sir Humphry Davy who had trouble settling with a name. He based the name on the mineral called alumina which was named by chemist Joseph Black in 1790. Joseph Black derived the name alumina from alum, a white mineral that was named by the French.These days it is commonly known as aluminum everywhere outside of the U.S. and Canada.
Which elements is most likely to have similar properties to those of sodium?
Each element has similar properties to the other elements in its group on the periodic table. Sodium is an alkali metal, and those are the elements in Group 1 of the periodic table of elements. We know that lithium, sodium, potassium, rubidium, cesium and francium all have similar chemical properties.
What element was isolated in 1808 by Sir Humphry davy?
Sodium. Humphry Davy succeeded in isolating sodium by electrolyzing molten sodium hydroxide in 1807.
Why did Sir Humphry Davy invent the lightbulb?

What did Humphry Davy discover?
He discovered how to separate elements by using electrolysis. He also discovered he element Aluminium. He proved that oxgen could not be obtained from HCL solution. He invented the miners' safety lamp.
What is potassium's date of discovery?
Potassium was discovered on October 6th 1807. Potasium was discovered when a chemist spent a lot of time thinking that our urine was somehow gold, and so he gathered a lot of urine and evaporated it to get the crystals! But this wasn't gold it turned out to be potasium!
Where did Humphrey Davy discover Carbon and diamond were the same element?
Humphrey Davy discovered that carbon and diamond were the same element in 1813 during his experiments on the electrolysis of molten salts. By passing an electric current through a mixture of molten salts and carbon, he was able to isolate elemental carbon, showing that diamond and carbon were chemically identical.

What element is know as K?
The element known as K is Potassium. Its atomic number is 19.
How many electrons does an atom potassium havew?
Finding the number of electrons in an atom is easy. You just have to know the atomic number of the element. The atomic number for Potassium is 19. That means Potassium has 19 electrons.
Molecular structure of potassium metal?
Potassium metal has a body-centered cubic crystal structure at room temperature. Each potassium atom is ionic, with a single valence electron in the outermost shell. In its pure form, potassium metal appears as a silvery-white metal that is highly reactive with water.
Who discovered or created boron?
Boron is not known to have been discovered by a single individual. It has been used since ancient times in compounds, but the pure element was first isolated and identified by Sir Humphry Davy and Joseph Louis Gay-Lussac in 1808.
What does k stand for in periodic table?
All symbols in the periodic table begin with UPPER CASE letters. K in the periodic table represents the element POTASSIUM.
Where does the name of potassium come from?
Potassium was discovered by Sir Humphrey Davy at 1807 in England. Origin of name: from the English word "potash" (pot ashes) and the Arabic word "qali" meaning alkali (the origin of the symbol K comes from the Latin word "kalium").Until the 18th century no distinction was made between potassium and sodium. This was because early chemists did not recognise that "vegetable alkali" (K2CO3, potassium carbonate, coming from deposits in the earth) and "mineral alkali" (Na2CO3, sodium carbonate, derived from wood ashes) are distinct from each other. Eventually a distinction was made.Well before potassium was recognized as an element, potassium carbonate was mixed with animal fat to make soap. The carbonate was made by extracting wood ash with water before concentration by boiling - hence the name "potash" for potassium salts.Potassium was isolated in 1807 by Sir Humphry Davy, who obtained it through the electrolysis of very dry molten caustic potash (KOH, potassium hydroxide). Potassium collected at the cathode. Potassium was the first metal isolated by electrolysis. Davy isolated sodium by a similar procedure later in 1807.Sometime prior to the autumn of 1803, the Englishman John Dalton was able to explain the results of some of his studies by assuming that matter is composed of atoms and that all samples of any given compound consist of the same combination of these atoms. Dalton also noted that in series of compounds, the ratios of the masses of the second element that combine with a given weight of the first element can be reduced to small whole numbers (the law of multiple proportions). This was further evidence for atoms. Dalton's theory of atoms was published by Thomas Thomson in the 3rd edition of his System of Chemistry in 1807 and in a paper about strontium oxalates published in the Philosophical Transactions. Dalton published these ideas himself in the following year in the New System of Chemical Philosophy. The symbol used by Dalton for potassium is shown below.
