How many neutrons are found in a stable isotope of uranium-235?
A stable isotope of uranium-235 contains 143 neutrons.
Is u235 stable?
No, uranium-235 (U-235) is not stable. It is a radioactive isotope that undergoes radioactive decay, emitting particles and energy in the process.
The time it takes for 50 percent of the nuclei in a radioactive sample to decay to its stable isotope is called?
The time it takes for 50 percent of the nuclei in a radioactive sample to decay to its stable isotope is called the half-life of the radioactive element. It is a characteristic property of each radioactive isotope and can vary greatly among different elements.
An element with the same number of protons and electrons as another atom of the element but with a different number of neutrons?
For the most part, yes the quantities of each are different. Light nucleii can have the same number of protons and neutrons and be stable enough to stay the same element (deuterium = 2H, 4He, 6Li , 10B, 12C, 14N, 16O, 20Ne, 24Mg, 28Si, 32S, 36Ar, 40Ca are stable), but a nucleus of a given element can sometimes have more or less neutrons, and be stable. Tin is the heaviest nucleus that has an isotope where #p = #n, and this isotope is very unstable
When an isotope decays over time and becomes a different element what is it called?
It is called radioactive decay. During this process, an unstable isotope loses energy or particles to become a more stable element.
How do you determine if an isotope is stable?
Isotopes are considered stable if they do not undergo radioactive decay over time. Scientists determine the stability of an isotope by measuring its half-life, which is the time it takes for half of the atoms in a sample to decay. If an isotope has a long half-life, it is considered stable.
What is the breakdown of a radioactive isotope into a stable isotope?
it must eject the extra nucleons and should be conveted into a stable isotope.
What is the stable isotope produced by radioactive decay is called?
The stable isotope produced by radioactive decay is called a daughter isotope.
What is the stable isotope that is formed by the breakdown of a radioactive isotope?
The stable isotope formed by the breakdown of a radioactive isotope is called a daughter isotope. This process is known as radioactive decay, where a radioactive isotope transforms into a stable daughter isotope through the emission of particles or energy.
Does the atomic number of an element determine its mass?
Not by itself. The mass number is the sum of the numbers of protons and neutrons in he nucleus for each isotope of the element, or for elements with more than one stable isotope is an average depending on the natural abundance of the stable isotopes of the element.
How is radioactive Isotope different from a stable isotope?
The radioactive isotope is disintegrated in time and emit radiations.
How is a radioactive isotope different from a stable isotope?
The radioactive isotope is disintegrated in time and emit radiations.
What is the stable produced by the radioactive decay of a parent isotope?
daughter isotope
Does uranium not have a stable isotope?
Uranium hasn't stable isotopes.
When a unstable isotope decays the daughter isotope that result is always a stable isotope true or false?
False. When an unstable isotope decays, the resulting daughter isotope may or may not be stable. Some daughter isotopes are stable, while others may still be radioactive and undergo further decay.
What is the stable isotope called?
Each isotope, stable or unstable, has a specific symbol; for example K-40 for potassium 40.
How many neutrons are found in a stable isotope of uranium-235?
