Which radioactive element has a half-life of 4.5 billion years?
Uranium
What is the name of the time required to change a part of a radioactive element to a stable element?
The name for the time required for half of a radioactive element to decay into a stable element is called the half-life. It is a constant value unique to each radioactive isotope, and it is used to measure the rate of radioactive decay.
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 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.
Which statement is true about half-lives a Different atoms of the same element have different half-lives. b Each radioactive isotope has its own half-life. c All radioactive nuclides of an element?
The correct answer is: Half-lives are not affected by temperature.
Which radioactive element has a half-life of 4.5 billion years?
Uranium
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.
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.
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.
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).
If a radioactive isotope had a half - life of 1 billion years how much of it would be left after 2 billion years?
1/4: Half would be gone after a billion years and half of that would be gone in another billion years. 1/4: Half would be gone after a billion years and half of that would be gone in another billion years. 1/4: Half would be gone after a billion years and half of that would be gone in another billion years.
What is argon's half-life?
Argon does not have a half-life because it is a stable element. Argon-40, a radioactive isotope of argon, has a half-life of about 1.25 billion years and is commonly used in radiometric dating.
What radioactive element is the time it takes for half of the radioactive atoms to decay?
The half-life
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 can half lives be shortened?
Half life of an element can't be changed.. It is a characteristic of a radioactive element which is independent of chemical and physical conditions.. Half life is that time in which half of radioactive sample( i.e., a radioactive element) decomposes. So no matter what amount you take half life of an element remains same.
What is a Radioactive Parent?
Radio active parent elements decay to stable daughter elements i.e. the radio active parent Potassium 40 decays to Argon 40 Each radioactive isotope has it's own half life A half life is the time it takes for the parent radioactive element to decay to a daughter product, Potassium 40 decays to Argon 40 with a half life of 1 1/4 billion years. Therin lies the problem of storing nuclear waste
What is the name of the time required to change a part of a radioactive element to a stable element?
The name for the time required for half of a radioactive element to decay into a stable element is called the half-life. It is a constant value unique to each radioactive isotope, and it is used to measure the rate of radioactive decay.
