The entered price of “Berkelium” per 9 ounces is equal to 4.99 .
How is berkelium used today?
Berkelium-249 (330-day half-life) has been widely used in the chemical studies of the element because it can be produced in weighable amounts that are isotopically pure by nuclear reactions beginning with curium-244. The only use of berkelium has been in the synthesis of heavier elements such as tennessine.
How much does chlorine cost per gram?

Where is berkelium most commonly found?
Source: Berkelium is produced in miniscule amounts in nuclear reactors such as the High Flux Isotope Reactor at Oak Ridge National Laboratory, Tennessee by nuclear bombardment of plutonium, curium or americium with alpha particles.
How hard is berkelium?
Berkelium is one of 15 actinides
Is chlorine man made or natural?
As chlorine is a natural element , it is found in the Earth itself. It is found on 7/10 of the Earth because it apparent in salt. The name for this combination is sodium chloride (NaCl). ... Although Chlorine is a natural element, in many man made reservoirs, the Chlorine is added to protect the water.
Is chlorine shiny or dull?

Is berkelium man made?
As with other actinide elements, berkelium tends to accumulate in the skeletal system. Berkelium is artificially produced , and has only been produced in relatively small amounts. It can be made through bombarding 241 Am, an isotope of americium, with alpha particles using a cyclotron.
Which is the rarest element on the Earth?
A team of researchers using the ISOLDE nuclear-physics facility at CERN has measured for the first time the so-called electron affinity of the chemical element astatine
Is berkelium radioactive?
Berkelium is a radioactive , silvery metal. Because it is so rare, berkelium has no commercial or technological use at present.
What 4 elements are named after planets?
Scientists named the elements uranium, neptunium, and plutonium after planets.
Why is element 105 named after a small town in Russia?
Dubnium is a synthetic chemical element with the symbol Db and atomic number 105. Dubnium is highly radioactive: the most stable known isotope, dubnium-268, has a half-life of about 28 hours. ... The element was formally named dubnium in 1997 after the town of Dubna, the site of the JINR .
What will berkelium react with?
Berkelium is a radioactive metallic element that is a member of the actinide group of elements. It is silvery in colour and its chemistry has been investigated to a limited extent and several compounds have been made. Berkelim metal is attacked by oxygen, steam and acids , but not by alkalis.
Can we live without chlorine?
It’s important for a living thing to balance its charge and one of the easiest ways to add negative charge is through chlorine. Also chlorine is important in forming hydrochloric acid which makes the stomach very acidic.
Why is chlorine bad?
Chlorine is a respiratory irritant , and inhaling it may cause pulmonary edema — an excessive buildup of fluid in the lungs that can lead to breathing difficulties. The gas can also cause eye and skin irritation, or even severe burns and ulcerations, according to the New York State Department of Health.
How does chlorine affect the human body?
When chlorine enters the body as a result of breathing, swallowing, or skin contact, it reacts with water to produce acids . The acids are corrosive and damage cells in the body on contact.
