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.
They are two natural elements, metals, extremely radioactive.
What else can I help you with?
Which element is more radioactive and explosive uranium or polonium?
Polonium is more radioactive than uranium, as it emits alpha particles that are highly energetic. However, uranium is more explosive due to its ability to undergo fission reactions, which release a large amount of energy quickly.
Which is more reactive polonium or plutonium?
Polonium is more reactive than plutonium. Polonium is a highly radioactive element and readily reacts with other elements or compounds, while plutonium is also radioactive but less reactive than polonium.
Is uranium a example of a radioactive element?
All elements have radioactive isotopes. Add a couple of hundred neutrons, and any stable element becomes radioactive.Technetium, promethium, and anything heavier than bismuth (element 83) will have radioactive decay.radio active elements can be uranium,radium,thorium,polonium,actinium etc.usually all elements of atomic number higher than 82 show radioactivity.
What is the odor of polonium?
Polonium does not have a distinct odor. It is a radioactive element that is odorless. The health risks associated with polonium stem from its radioactivity rather than any smell it may have.
How do Polonium smell?
Any person tasted this extremely poisonous element !
Which element is more radioactive than uranium?
polonium, radium, plutonium and many others
What elements did Marie Curie discovered?
She discovered the elements Polonium, which was named after her homeland, and radium. Polonium is 4x more radioactive than uranium and radium is 10x more radioactive than uranium.
Which element is more radioactive and explosive uranium or polonium?
Polonium is more radioactive than uranium, as it emits alpha particles that are highly energetic. However, uranium is more explosive due to its ability to undergo fission reactions, which release a large amount of energy quickly.
What is more radioactive than pure uranium?
Many radioactive isotopes are more radioactive than the naturally occurring uranium isotopes:All fission product isotopes are more radioactive (e.g. iodine-131, strontium-90)Most radioactive isotopes in the uranium --> lead decay chain are more radioactive (e.g. radium, radon, polonium)Plutonium is more radioactiveTritium is more radioactiveCarbon-14 is more radioactiveArtificially produced uranium isotopes are more radioactive (e.g. uranium-233, uranium-236)etc.
When and how polonium was discovered?
Studying residues of uranium ores Marie Curie found that these residues are more radioactive than uranium; she attributed this radioactivity to an unknown element. She isolated this element and named this element polonium.
Why did Marie Curie discover polonium?
Studying residues of uranium ores Marie Curie found that these residues are more radioactive than uranium; she attributed this radioactivity to a new element. She isolated this element and named polonium.
Why did Marie Curie discover polonium and radium?
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.
How much more active is polonium than uranium?
Polonium is more radioactive than uranium as it emits alpha particles at a much higher rate. Polonium-210, for example, has a half-life of only 138 days compared to billions of years for some isotopes of uranium.
How did Pierre and Marie Curie discovered the presence of radioactive elements other than uranium?
Polonium and radium are discovered in wastes from uranium minerals, after uranium separation. The important radioactivity of these residues (without uranium) warned the two about the possible existence of other radioactive elements.
How did Marie Curie find out polonium?
Studying residues of uranium ores Marie Curie found that these residues are more radioactive than uranium; she attributed this radioactivity to unknown elements. She isolated these elements and named these elements polonium and radium.
Why did Marie Curie invent polonium?
Polonium was discovered - not invented !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.
What did Marie Curie do polonium?
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.
