Polonium was discovered by Marie Curie and Pierre Curie in 1898.
Radium was discovered by Marie Curie, Pierre Curie and G. Bemont also in 1898.
Studying residues of uranium ores Marie Curie and Pierre Curie found that these residues are more radioactive than uranium; they attributed this radioactivity to unknown elements. They isolated these elements and named these elements polonium and radium.
The element you are referring to is radium, which was discovered by Marie and Pierre Curie in 1898. Radium is a highly radioactive element and is known for its luminescent properties.
she discovered radium and polonium, two radioactive elements that they extracted chemically from pitchblende ore
polonium and radium
Uranium is a common radioactive element that is commonly used in warships and many electricity - powering power stations.
Marie Curie and her husband discovered both Radium and Polonium. Unfortunately her later death is attributed to the exposure to radiation during her lifetime.
radium and polonium are the elements discovered by madame curie

First element known to be radioactive?
Uranium is the first element known to be radioactive. It was discovered by Henri Becquerel in 1896.
What is the meaning of francium?
Francium is a highly radioactive alkali metal element with the atomic number 87 and symbol Fr. It is the second rarest naturally occurring element in the Earth's crust and is extremely unstable, making it difficult to study. Francium was discovered in 1939 by Marguerite Perey.
Which element is radioactive and synthetic?
Plutonium is a synthetic element that is radioactive. It does not occur naturally in nature and must be artificially produced through the nuclear fission of uranium.
Because francium breaks down and gives off particles and energy it is a what?
Francium is a radioactive element that undergoes decay to form other elements, releasing particles and energy in the process. Therefore, it is considered a radioactive element.
Is berkelium radioactive?
Yes, berkelium is a radioactive element. It is a transuranic element that is usually produced in nuclear reactors and decays through the emission of alpha particles.
What radioactive element was discovered by Pierre and Marie Curie?
The Curies discovered two radioactive elements: polonium and radium.
One of the most radioactive elements discovered by the curies was uranium?
No. The Curies did not discover uranium. They discovered polonium and radium, of which polonium is more radioactive.
Radioactive element that was found in France?
Radium was discovered in France by the Curies, in samples of ore from the Austrian Empire, in 1898.
What element was named for the couple who discovered radium?
Curium was named after the Curies.
Do radium and radius have the same meaning?
Radium and radius do not mean the same thing. Radium is an element in group 2. It is radioactive and was discovered by the Curies. Radius is either the distance from the centre of a circle to its circumference, or a bone in the forearm.
Where was chemical element radium discovered?
The Curies published their paper, describing the newly discovered element -- that they named "radium" -- on 1898 December 26. Their work was conducted in Paris France.
Where is polonium taken?
This element Po(84) was the first one discovered by the Curies while they were investigating the cause of pitchblenderadioactivity (1898). The pitchblende, after removal of the radioactive elements uranium and thorium (Th), was more radioactive than both the uranium and thorium put together. This spurred the Curies on to find additional radioactive elements. The Curies first separated out polonium from the pitchblende1), and then within a few years, also isolated radium.1) The type locality for this ore is Jáchymov in the Czech Republic, from where F.E.Brückmann described the mineral in 1727.Pitchblende from the Johanngeorgenstadt deposit in Germany was used by M.Klaproth in 1789 to discover the element uranium.
What is the rate of decay of a radioactive element is measured by?
By Becquerels, which is one disintegration per second, or by curies, which is 3.3x1010 disintegrations per second.
Who discovered the first radioactive element?
Marie Curie and Pierre Curie discovered the first radioactive element, radium, in 1898.
What is the radioactive element discovered by Madam Curie?
Polanium
What was one of the most lasting result of the Curies' research?
On a purely foundational level, the Curies were the first to show that atoms were not unchangeable -- that radioactivity was not a chemical reaction but, instead, comes from the element itself. Radium, which the Curies discovered, is a highly radioactive source of alpha particles. It was used in Rutherford's experiment that showed the atom had a nuclear structure. For many decades, radium was also used as a means to kill tumors.
Who discovered the radioactive element polonium?
Marie and Pierre Curie
