My element 's name is Barium; the origin of Barium 's very direct name is from the Greek word “Barys,” meaning heavy, due to it 's high density. The Chemical symbol that represents Barium is “Ba,” and the reason from it 's choosing is due to the Perdoic Table using the first and second letter of an element if the very first letter has been taken (Although, some elements are Greek, Latin, etc). Barium is found on the Earth 's crust in with familiar minerals such as Aragonite, Calcite, Chalk, Limestone, Marble, Travertine, Magnesite, and Dolomite. The history of Barium started in the 1600s in Bologna, Italy, a shoemaker named Vincenzo Casziarolo found some very unusual pebbles. If the pebbles were heated in the daytime, they would shine during the night. The pebble was actually the mineral Barium Sulfate. …show more content…
Around the 1760s, Barium Sulfate ( Bologna stone) became very well-known and was investigated by Carl Scheele. Suddenly, he realized it was sulfate of an unknown element. Meanwhile, mineralogist Dr. William Withering had found another heavy mineral in the Lead Mine in Cumberland, which was actually a lead ore. Naming the mineral Witherite, it was soon shown to be Barium Carbonate. 1808, Humphry Davy at the Royal Instiution in London was using the process of smelting with carbon, and produced the electrolysis of Barium Hydroxide. The physical properties of Barium are solid, pale yellow, shiny, and a malleable metal in room tempature. The melting point and boiling give off a pale-green yellow. Some very interseting chemical properties of Barium is that it is malleable, flammable, very active, Alkaline Earth Metal Group, can be toxic, can react to water and other acids, but finally, to prevent such reacting, Barium is stored under Kerosense, Petrolem, or some other oily
Who discovered it? How did they discover it? It was not Thomas Jefferson and it was not George Washington, so who was it? On the 17th of January 1706, a man by the name of Benjamin Franklin was born.
I was wondering around for about another hour or so judging on the position of the sun. I was now wondering around for probably another 30 minutes when I came across a stone
Jewel Cave is located in the Black Hills of South Dakota. The Black Hills were formed during the Tertiary Lamanide Oroginy. (See Figure 2 and 7). The Black Hills are doubly asymmetrical anticlines that are plunging to form a dome. Two rock types are from the Tertiary and the Quaternary period and are starting to intrude into the older rock types.
The Element Vanadium and its Uses Vanadium was discovered by Andrés Manuel del Rio, a Mexican chemist, in 1801. Rio sent samples of vanadium ore and a letter describing his methods to the Institute de France in Paris, France, for analysis and confirmation. Unfortunately for Rio, his letter was lost in a shipwreck and the Institute only received his samples, which contained a brief note describing how much this new element, which Rio had named erythronium, resembled chromium. Rio withdrew his claim when he received a letter from Paris disputing his discovery. Vanadium was rediscovered by Nils Gabriel Sefstrôm, a Swedish chemist, in 1830 while analyzing samples of iron from a mine in Sweden.
My group and I determined that each of the powders state was solid, all of them were a white colour, and they were all opaque. 3. What other physical properties could have helped to identify te mysery powder? Why were these properties not tested in this activity?
There are about 10 Isotopes known to us and half of them are stable. This element is a
Outlines the physical properties of the isotope The Physical properties of Plutonium 239 Colour: Plutonium is an actinide metal of silver colour, it forms an outer coating of dull grey appearance and begins to tarnish when exposed to oxygen. Melting Point: 639.5°C Boiling point: 3228°C. Density: 19.816 g/cm3 (at room temperature) Half-Life: 24110
They had to light lanterns to see during the day because of all the dust when they did have
German scientists claim to have created a stable isotope of protactinium in 1916 but Cranston said he had actually discovered it in 1915, but his notes were locked away while he was on duty in World War I. This chain of events has lead to some debate over the actual discovery dates of the element but it is generally agreed that it was discovered around 1917.
To illustrate “Its heat lingered persistently, and Nahum declared it had glowed faintly in the night.” (H.P. Lovecraft, 1927, p.3) When scientists took a piece to study, they noticed that meteor appeared to have a plastic consistency. They then took it back to the college and began
When looking up who found this element it said that no one specific found the element and is still unknown about its creation into the periodic table. The first encounter of Silver was in 4000 BC which was one of the earliest elements found in the periodic table and it was discovered in Greece and then modern Turkey. It can be found now
The land started to shake violently as if something were trying to escape an underground tomb. All of a sudden, blood orange streams of lava started to spew out all around him. He saw it, a bright strike of cobalt blue, as clear as the Hawaiian water on a peaceful day. It streaked across the hardened molten rocks, lashing out like a rabid dog. “Lighting!”
Plutonium is a transuranic radioactive chemical element with symbol Pu and atomic number 94. It is an actinide metal of silvery-gray appearance that tarnishes when exposed to air, and forms a dull coating when oxidized. The element normally exhibits six allotropes and four oxidation states. It reacts with carbon, halogens, nitrogen, silicon and hydrogen. When exposed to moist air, it forms oxides and hydrides that expand the sample up to 70% in volume, which in turn flake off as a powder that is pyrophoric.
Did you know that there are 118 elements on the periodic table? The first element appeared in the 1400’s This element was called bismuth. Since then there have been 117 other types of elements that have been discovered. Some of the elements that appear on the table are radioactive while others are not.
Periodic Table Summary Jordan King - Periodic Table of Harry Potter Characters The periodic table project has been one of my favorite projects so far in my school career, mostly because I was free to choose a topic that interests me. The topic I picked was Harry Potter Characters. I chose it because my all-time favorite series of books is the Harry Potter collection and it would be really handy for reference, especially for people who haven’t seen the movies or read the books. You’re welcome non-Harry Potter fans!
