Elements that are active strongly nonmetallic and react readily with metals to form salts are called what?
Elements that form salts by combining with metals are called halogens. All synthetic elements are radioactive. Elements that lie along the stair step line of the periodic table are metalloids.
When was phosphorus created?
Phosphorus was discovered in 1669 by a German scientist called Hennig Brand.
What is the section of elements that are placed outside of the periodic table called?
The elements that are placed outside of the periodic table are called transactinides. These elements are usually placed in a separate row below the main table and are synthetic elements that do not occur naturally on Earth.
Who is the scientist who first proposed the use of chemical symbols?
No single scientist has devised the symbols of the elements. An organization called the International Union of Pure and Applied Chemistry (IUPAC) has determined the symbols of the elements on the Periodic Table.
Compare the role of nuclear fusion in the formation of the earth's naturally occurring elements and in the creation of synthetic elements in the laboratory?
The range of elements found on earth were formed by some supernova explosion in the distant past, and somehow the earth was formed from the debris and then captured by the sun. Fusion must have been involved though the exact course of these events can only be surmised. Nuclear fusion has not been used on earth to create synthetic elements, and in fact has only been produced in a few places for very short times, less than one second. You are probably thinking of nuclear fission, where operation of nuclear reactors does produce synthetic elements such as plutonium. These are called the transuranic elements.
To make most synthetic elements scientist use powerful machines called?
particle accelarators
What are elements called that are created by main in a laboratory?
Synthetic or man-made elements. Obviously synthetic sounds significantly cooler.
What are element that are not naturally occurring elements called?
Synthetic
Who was the scientist that organized the elements into a table that you use today and what was the table called?
i don't know the scientist but it is the periodic table of the elements
What are elements that can not be found on earth and can be created called?
Synthetic elements are not found in nature but are created in laboratories.
The term used to describe elements that are synthetic or man made?
They are called artificial chemical elements.
Do Elements 3 through 12 contain metals called?
synthetic
What are elements called when they are found in nature?
Elements found in nature are referred to natural elements, as opposed to synthetic, which are man made.
Scientists make elements heavier then uranium in machines called?
Particle accelerators and nuclear reactors
What name is given to elements with an atomic number greater than 92?
They are called the trans-uranic elements. They are either synthetic or the rare product of radioactive decay.
What studies atoms and molecules?
A scientist that studies elements atoms and molecules is called a Chemist.
Elements that are active strongly nonmetallic and react readily with metals to form salts are called what?
Elements that form salts by combining with metals are called halogens. All synthetic elements are radioactive. Elements that lie along the stair step line of the periodic table are metalloids.
