What does thorium decay into?

Thorium- 228 is a decay product of radium-228, and thorium-228 decays into radium-224. The radiation from the decay of thorium and its decay products is in the form of alpha and beta particles and gamma radiation.

What is the new element that uranium becomes after decay?

The half-life of uranium-238 is 4.5 billion years. It decays into radium-226, which in turn decays into radon-222.

What is the term for elements heavier that uranium?

Superheavy elements, also known as transactinide elements, transactinides, or super-heavy elements, are the chemical elements with atomic numbers greater than 103. By definition, superheavy elements are also transuranic elements, i.e. having atomic numbers greater than that of uranium (92).

Does uranium decay into thorium?

Uranium is the principal fuel for nuclear reactors and the main raw material for nuclear weapons. Uranium-238 decays by alpha emission into thorium-234, which itself decays by beta emission to protactinium-234, which decays by beta emission to uranium-234, and so on.

Does uranium decay to thorium?

A nucleus of uranium 238 decays by alpha emission to form a daughter nucleus, thorium 234. This last isotope changes slowly (with a half-life of 245,000 years) into thorium 230, yet another unstable nucleus. Any such decay chain is only stopped by the formation of a stable nucleus.

What is decay reaction?

In a nuclear decay reaction, also called radioactive decay, an unstable nucleus emits radiation and is transformed into the nucleus of one or more other elements. Nuclear decay reactions occur spontaneously under all conditions, whereas nuclear transmutation reactions are induced.

What element does uranium 235 decay into?

thorium-231
Encyclopædia Britannica, Inc. Decay of uranium-235 into thorium-231 and an alpha particle. Larger, more massive nuclei like uranium-235 become more stable by emitting an alpha particle, which is a helium nucleus composed of two protons and two neutrons. This process is known as alpha decay.

What are the heaviest elements called?

oganesson
The heaviest element, in terms of atomic weight, is element 118 or oganesson. The element with the highest density is osmium or iridium.

How are elements heavier than uranium made?

Scientists generally artificially create elements that are heavier than uranium, which is done by adding protons into an atomic nucleus through nuclear fusion reactions. Generally speaking, the more protons and neutrons that are added into an atomic nucleus, the more unstable an atom becomes.

What are the byproducts of the decay of uranium 238?

Uranium 238 spontaneously decays to Thorium 234 and an alpha particle Thorium decays to Protactinium and so on, all the way down to lead Various byproducts are alpha, beta and gamma radiation Particles (and gamma rays) leave the nucleus with a lot of energy (high speed)

What is the heaviest element with a stable radioactive decay?

Lead, atomic number 82, is the heaviest element to have any isotopes stable (to the limit of measurement) to radioactive decay. Radioactive decay is seen in all isotopes of all elements of atomic number 83 (bismuth) or greater.

What is the half-life of uranium 238 and uranium235?

The half-life of uranium-238 is about 4.47 billion years and that of uranium-235 is 704 million years, making them useful in dating the age of the Earth . Many contemporary uses of uranium exploit its unique nuclear properties.

What is the difference between uranium and plutonium in a bomb?

But the type of uranium and plutonium for bombs is different from that in a nuclear power plant. Bomb-grade uranium is highly enriched (>90\% U-235, instead of about 3.5-5.0\% in a power plant); bomb-grade plutonium is fairly pure (>90\%) Pu-239 and is made in special reactors.
