How many years will it take for 10 g of radioactive uranium to decay into 5 g of radioactive uranium?
5,730 years
When does Uranium-235 become unstable?
Uranium 235 is unstable because it is a radioactive isotope. This means that it is constantly decaying and emitting radiation. The reason it is unstable is because it has too many neutrons in its nucleus. The neutron is a unstable particle, and when there are too many of them in one place, they can cause problems. When uranium 235 decays, it emits alpha particles, which are high-energy particles that can damage DNA and cause cancer.
How many radioactive isotopes does uranium have?
All of them.
How many isotopes of polonium are part of the decay?
Each isotope has a specific radioactive decay.
What causes Uranium to be radioactive?
The stability depend on the ratio between protons and neutrons; uranium has too many neutrons.

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 is more radioactive than pure uranium?
Many radioactive isotopes are more radioactive than the naturally occurring uranium isotopes:All fission product isotopes are more radioactive (e.g. iodine-131, strontium-90)Most radioactive isotopes in the uranium --> lead decay chain are more radioactive (e.g. radium, radon, polonium)Plutonium is more radioactiveTritium is more radioactiveCarbon-14 is more radioactiveArtificially produced uranium isotopes are more radioactive (e.g. uranium-233, uranium-236)etc.
What does uranium become when it decays?
If we use uranium-238 as our starter isotope, what happens is that a nuclear decay event happens (in this case an alpha decay) and the U-238 transforms into a daughter isotope thorium (Th-234). The half-life of this transition is 4.5 billion years. Thorium-234 then undergoes a decay. And the process continues until a stable isotope is created as the last daughter of a decay chain. Note that there will be different half lives for the transition events, and the modes of decay will vary depending on what daughter is now the parent in the next decay event. Use the link below to see all the steps. The chart will show the whole chain including the half-life of isotope undergoing decay, the decay mode, and the daughter. Follow along using the keys and the process will reveal itself.

What is the name for the emission of rays and particles by a radioactive material?
The name for the emissions of rays and particles by a radioactive material are called radioactive decay. There are many different types of radioactive decay that emit different rays and particles.
