What is the definition of the word polonium?
Polonium is a very rare chemical element. It has the atomic number 84. It is produced when uranium decays and is a naturally radioactive metallic element.
What is Plutonium classification?
Platinum is a metallic, solid, radioactive chemical element; now it is considered a natural element. Plutonium is a member of the actinides group.
What characterizes a radioactive element?
As radioactive element is an element that is on the Priodic Table of Elements. A Radioactive Element is usually radioactive.
How do you use radioactive element in a sentence?
A radioactive element is one that discharges radiation. Uranium is a radioactive element. A radioactive element is very dangerous if you don't have protective clothing. You should never go near a radioactive element.
Is an iron a metallic element or a mixture or a compound or a non metallic element?
Yes, because it is definitely an element and it is made from a metal thus making it a metallic element
This is a naturally radioactive metallic element?
francium, an alkali metal
Is barium a metallic element highly radioactive and chemically?
No. It is not radioactive.
What is the definition of the word polonium?
Polonium is a very rare chemical element. It has the atomic number 84. It is produced when uranium decays and is a naturally radioactive metallic element.
Is tin natural or lab created?
Tin is a naturally occurring metallic element. It is only created in supernova explosions. Radioactive tin can be created in nuclear reactors.
What is a naturally occurring element that is radioactive?
Uranium and Plutonium
What is a colorless naturally occurring radioactive inert gaseous element formed by radioactive decay?
It is radon that we see formed from the decay of naturally radioactive substances in the earth's crust.
Where was element 98 discovered or made?
First made in 1950 at the University of California. It is a radioactive metallic chemical element
What is an intensely radioactive metallic element that occurs in minute amounts in uranium ores?
Radium and polonium
Is uranium non metallic or metallic?
Uranium is a natural chemical element, radioactive, dense, atomic number 92.Uranium is a solid metal.
The process by which one element naturally changes into another is called?
It is radioactive decay.
What is Plutonium classification?
Platinum is a metallic, solid, radioactive chemical element; now it is considered a natural element. Plutonium is a member of the actinides group.
How many protons are needed for a element to be naturally radioactive?
Whether an ISOTOPE (not element) is naturally radioactive depends not only on the number of protons, but also on the number of neutrons. For EVERY element, there are radioactive isotopes.There has to be a certain relationship between the number of protons and the number of neutrons, but the relationship isn't a simple one.
