What is radioactive decay with Earth's crust?
When a radioactive isotope of an element releases a radiation particle the sub-atomic structure of it's nucleus changes. If an alpha particle is released the nucleus loses 2 protons and 2 neutrons, making it a new, lighter and smaller atom and therefore a different element. If a beta particle is released one of the neutrons in the nucleus releases an electron and becomes a proton so the atom's mass does not change significantly but t does become a different element.
Are Nuclear wastes non biodegradable?
Actually, they are biodegradeable, sort of. Radioactive materials do decay, or become weaker over time. Eventually they become inert, or non-radioactive. The problem is some radioactive isotopes take tens or even hundreds of thousands or millions of years to decay. The decay rate of a radioactive element is measured in half-lives. After one half-life, half of the radioctivity is gone. Take an element with a half-life of ten years. After ten years, there is half of the radioactivity present. After 20 years, one quarter, after 30 years, one eighth, and so forth. Eventually the level will fall to the point it poses no danger. Plutonium-239 has a half-life of 24,000 years. Uranium-235, used in nuclear reactors, has a half-life of 713,000,000 years.
Importance of radioactive decay?
it is used by scientist to to calculate a rock's age
Who discovered radioactive decay in 1898?
ernest Rutherford _______________________________________________________________ Radioactive decay was actually discovered in 1896 by Henri Bacquerel. Ernest Rutherford discovered the formula of radioactive decay (Such as the falk-life, differences between alpha and beta decay and even how the elements become new elements after the decay), but he did not discover the radioactive decay himself.
How does radioactive decay become radioactive?
That depends on the specific radioisotope. For instance, uranium 238 emits an alpha particle during radioactive decay, reducing the number of protons and neutrons in the nucleus by 2 each and producing thorium 234. On the other hand, carbon 14 emits a beta particle (an electron) during radioactive decay, decreasing the number of neutrons and increasing the number of protons by 1 each and producing nitrogen 14. There are quite a few other examples with different changes depending on the type of radioactive decay.
What would happen to an atom if the number of protons in the nucleus changed?
It would become a different element. It could become radioactive.
Are all elements periodically change to become new element s?
No. Only radioactive elements, which undergo radioactive decay can change to different elements.
Does a radioactive element become stable after its mass number become less than 82?
Not always -- Hydrogen-3 is radioactive, for example.
What does it mean if an element it radioactive?
this is because an element is sometimes never radioactive but one may be made just to be radioactive this is because an element is sometimes never radioactive but one may be made just to be radioactive
How can element 92 become element 83?
Through radioactive decay, because Uranium (element 92) is unstable.
What is the process by which an element slowly decays over time?
It is through radioactive decay that a quantity of an unstable element will decay over time. A material that is unstable will undergo this process, and the sample is said to be radioactive.
When an atom undergoes radioactive decay when does it become a completely different element?
An atom of a given isotope will undergo radioactive decay whenever it feels like it. No joke. The nucleus of a radioactive isotope is unstable. Always. But that atom has no predictable moment of instability leading immediately to the decay event. We use something called a half life to estimate how long it will take for half a given quantity of an isotope to undergo radioactive decay until half the original amount is left, but this is a statistically calculated period. No one knows how long it will take a given atom of a radioactive isotope to decay, except that those with very short half lives will pretty much disappear relatively quickly.
If chromium undergoes gamma decay what does it become?
If chromium undergoes gamma decay, it remains as chromium. Gamma decay is a type of radioactive decay where a nucleus releases gamma rays to reach a more stable state, but the identity of the element remains the same.
How uranium nucleus become stable?
Being radioactive, uranium is not a stable element.
If an element is radioactive is it's nucleus unstable?
Yes,The element is radioactive due to the instability of its nucleus.See the related question below for more information.
Does the identity of an atom change during radioactive decay.why or why not?
Well, when an atom undergoes radioactive decay, it can change into a different element. This happens because the nucleus of the atom becomes unstable and releases particles or energy to become more stable. So, while the identity of the atom may change, it's all just a part of nature's way of finding balance and harmony in the universe.
What happened to the part of the plutonium that is no longer ther?
Plutonium is a radioactive element that decays over time, transforming into other elements through a series of radioactive decays. When plutonium decays, it releases energy in the form of radiation and transforms into a different element. This process continues until the plutonium is no longer present.
