For decays by alpha emission use the general formula:
A/Z X --> 4/2 He + A-4/Z-2 Y
*Where A is Atomic Mass and Z is atomic number.
So for U-238
238/92 U --> 4/2 He + 234/90 Th
What else can I help you with?
Protactinium-231 decays by emitting an beta particle and a gamma ray. What daughter nuclide is formed in this process?
The alpha decay of protactinium-231 will result in the appearance of actinium-227. It might look like this if we wrote it out: 91231Pa => 24He + 89227Ac The alpha particle is a helium-4 nucleus, so we write it that way.
What is the identity of the nuclide produced when thallium-201 decays by electron capture?
When thallium-201 decays by electron capture, it transforms into mercury-201. In electron capture, a proton in the nucleus combines with an inner-shell electron to form a neutron and a neutrino. The resulting nuclide is one atomic number less with the same mass number.
What are the particles produced when a positive pion decays?
When a positive pion decays, it produces a muon and a neutrino.
What is the equation for beta decay of uranium-237?
The beta decay of uranium-237 can be represented by the equation: (^{237}{92}U \to ^{237}{93}Np + e^- + \bar{\nu_e}) where (^{237}{92}U) decays into (^{237}{93}Np), an electron (e^-), and an electron antineutrino (\bar{\nu_e}).
What radionuclide decays to Br-73 by positron emission?
Work backwards. Positron emission means (essentially) a proton decayed into a neutron/positron pair. The mass number remains the same, but the atomic number goes down one to Bromine. Krypton has an isotope that fits this bill.
What is the name of the daughter nuclide?
The daughter nuclide is the atom or atoms that result when a parent nuclide decays through emission of ionizing radiation or through fission.
The uranium-235 decay series begins with the emission of an alpha particle If the daughter decays by beta emission what is the resulting nuclide?
Uranium-235 will not beta decay first. If you google "Chart of Nuclides" you can follow the entire decay chain yourself using each isotope's most likely decay type.
Protactinium-231 decays by emitting an beta particle and a gamma ray. What daughter nuclide is formed in this process?

What is the effect of beta decay on composition of a nucleus?
Commonly the parent nuclide decays by the beta emission. In addition to that; inside the nuclei decay chain will consistently have half-lives!
Which inert gas is radioactive?
Radon is the only naturally occurring radioactive inert gas. Its most stable isotope, radon-222, decays through alpha particle emission. It is produced as a decay product of uranium and thorium in the Earth's crust.
What is the identity of the nuclide produced when thallium-201 decays by electron capture?
When thallium-201 decays by electron capture, it transforms into mercury-201. In electron capture, a proton in the nucleus combines with an inner-shell electron to form a neutron and a neutrino. The resulting nuclide is one atomic number less with the same mass number.
When thorium decays by producing an alpha praticle the product nuclide is?
The decay of thorium by alpha decay the resultant nuclide is the element radium. The specific nuclide of radium cannot be determined unless we know which specific nuclide of thorium underwent alpha decay.
What is it about uranium that makes it radioactive?
Uranium is radioactive because its atomic structure is unstable, leading to the emission of particles and energy as it decays. This process is known as radioactive decay, which releases radiation in the form of alpha and beta particles, as well as gamma rays.
When a uranium atom decays radioactivity to become protactinium the radiation emitted is?
Some possible decays:- U-231------------Pa-231 (by electron capture)- U-229------------Pa-229 (emission of a beta particle)- U-228------------Pa-228 (by electron capture)
When uranium atom decays radioactively to become protactinium the radiations emitt ed are?
Some possible decays: - U-231------------Pa-231 (by electron capture) - U-229------------Pa-229 (emission of a beta particle) - U-228------------Pa-228 (by electron capture)
When will an unstable nuclide stop emitting radiation?
An unstable nuclide will stop emitting radiation when it decays into a stable daughter nuclide. This decay process continues until a stable configuration is reached, which may take seconds to billions of years depending on the nuclide.
How is radon gas is produced?
Radon gas is produced from the natural decay of uranium in soil, rocks, and water. When uranium breaks down, it forms radium, which then decays to produce radon gas. Radon can seep into buildings through cracks in the foundation or gaps in walls and floors.
