Which radioactive element has a half life of 4.5 billion years?
The radioactive element with a half-life of 4.5 billion years is Uranium-238. It is commonly used in radiometric dating to determine the age of rocks and materials on Earth due to its long half-life.
How many years will it take for 10g of radioactive uranium to decay into 5g of radioactive uranium?
Depending on the isotope: - for 235U: 7,038.108 years - for 238U: 4,468.109 years etc.
What elements name is made up a term that refers to a billion years?
The answer is Gallium Ga stands for giga-ani meaning 'billion years' and is also the periodic symbol for this element.
What element that has no stable isotopes?
Technetium (Tc) is the element that has no stable isotopes. All of its isotopes are radioactive with half-lives ranging from minutes to millions of years.
What element is used to make nuclear weapons?
Uranium-235Uranium-233Plutonium-239DeuteriumTritiumAs tritium is radioactive with a short halflife (12 years), weapons using it age rapidly possibly becoming unreliable. Therefore it is normally produced from Lithium (in the form of Lithium Deuteride) by fission neutron bombardment just before fusion is initiated.
How much of the radioactive element will be left one billion years from now?
That depends on the "half-life" of that particular radioactive element, which the question forgot to state. They're all different. Various radioactive elements have half-lives ranging from microseconds to millions of years.
Which radioactive element has a half life of 4.5 billion years?
The radioactive element with a half-life of 4.5 billion years is Uranium-238. It is commonly used in radiometric dating to determine the age of rocks and materials on Earth due to its long half-life.
What if your cat is radioactive with the same halflife as carbon 14. how many years will it take for three fourths of your cat to degrade?

What Element stays radioactive for millions of years?
The element that can stay radioactive for millions of years is plutonium. This is where most nuclear power plant energy comes from.
What is the range of half-lives of different radioactive element?
It would be quite difficult to list all radioactive elements and their half lives in this area. Lithium 5 has a half life of about a trillionth of a second. Uranium 238 has a half life of about 4.7 billion years. Since the world is about 4.2 billion years, over half the Uranium 238 is still around. The first element in the Periodic Table, Hydrogen, has a radioactive form, Hydrogen 3. It has a half life of about Twelve and a half years. Helium has a radioactive form, Helium 5. It's half life is a trillionth of a second. Then you get to elements with different radioactive isotopes. You will need to look them up in a handbook. Tin is the element with the most isotopes.
How do you identify beta decay?
A sample of 187 rhenium decays to 187-omium with halflife of 41.6 billion years. If all 188 osmium are normalized isotopes.
Which lanthanide element and which transition element have only radioactive isotopes?
All or almost all elements have radioactive isotopes if artificial isotopes are included. Among the naturally occurring elements, uranium, polonium, radium, and thorium have naturally occurring radioactive isotopes on earth.
What element was named after the planet Pluto and stays radioactive for millions of years?
Plutonium is the element named after the planet Pluto. It is a radioactive element with a half-life of thousands of years, not millions.
How long will it take half of a radioactive sample to decay?
The time it takes for half of a radioactive sample to decay is known as the half-life. Each radioactive element has a unique half-life, which could range from fractions of a second to billions of years. The half-life remains constant regardless of the size of the initial sample.
What is the half-life of every radioactive element?
The same element can have different half-lives, for different isotopes. You can find a list at the Wikipedia article "List of radioactive isotopes by half-life". This list is NOT complete; a complete list would have about 3000 nuclides (that is, isotopes).
What radioactive substance has the longest half-life?
One of the radioactive substances with the longest half-life is thorium-232, with a half-life of about 14 billion years. Another example is uranium-238, which has a half-life of about 4.5 billion years.
When was the element neon invented?
13.7 billion years ago.
