What is the particle emitted when neodymium-144 decays into promethium-144?
When neodymium-144 decays into promethium-144, it emits a beta particle. This process involves the transformation of a neutron into a proton within the neodymium nucleus, resulting in the emission of an electron (the beta particle) and an antineutrino. The increase in the proton number by one changes the element from neodymium to promethium while the atomic mass remains essentially the same.
Hat particle is release when Ga-75 decay to Ge-75?
When Gallium-75 (Ga-75) decays to Germanium-75 (Ge-75), it undergoes beta decay, where a neutron in the Ga-75 nucleus is converted into a proton, emitting a beta particle (an electron) and an antineutrino. This process increases the atomic number of the element from 31 (Gallium) to 32 (Germanium), while the mass number remains the same. The emitted beta particle is the key particle released during this decay process.
How many decays per second is in a curie?
Curie: A unit of radioactivity equal to 3.7 � 10^10 Disintegrations (decays) per second.
Where do they find Unununium?
Unununium, now known as roentgenium (Rg), is a synthetic element and not found in nature. It was first created in a laboratory setting in 1994 by a team of Russian and American scientists at the GSI Helmholtz Centre for Heavy Ion Research in Germany. Due to its highly unstable and radioactive nature, roentgenium can only be produced in minute amounts through particle accelerator experiments. Its short half-life means it decays rapidly, making it impossible to find in the environment.
After 7 minutes a 53 g sample of plutonium decays to 36 g how long will it take for the sample to decay to 13 of its original amount?
It will take 25.0898 minutes, approx.
What particle is emitted when Pu 240 decays to U 236?
An alpha particle is emitted when Pu-240 decays to U-236. It consists of two protons and two neutrons and is commonly emitted in alpha decay processes.
What particle is emitted when P-32 decays to S-32?
When P-32 decays to S-32, a beta particle is emitted. This beta particle is an electron released during the conversion of a neutron into a proton within the nucleus of the atom.
What type of particle is emitted when a U-235 decays to Np-235?
It is negative beta particle emitted by a uranium nucleus and converting it to neptunium nucleus.
What kind of radiation is emitted when polonium decays to astatine?
Polonium, which has an atomic number of 84, decays to astatine, which has an atomic number of 85, a negative beta particle is emitted.
When U-238 decays to th-234 what has been emitted?
An Alpha particle, and associated gamma radiation from the excited nucleus.
Which particle is emitted when an atom OF 85Kr spontaneously decays?
When an atom of 85Kr spontaneously decays, it emits a beta particle. This decay process involves the transformation of a neutron into a proton, with the emission of an electron and an antineutrino.
What type of particle is emitted when U-235 decays to Np-235?
It is the reverse: Np-235 decay to U-235 by electron capture.
What particle is emitted when Pt-190 decays to Os-186?
An alpha particle is emitted when Pt-190 decays to Os-186. An alpha particle has a mass number of 4, and an atomic number of 2. When Pt-190 decays to Os-186, the mass number drops by 4, showing that an alpha particle is emitted, along with energy. The other form of particle that could be emitted is a beta particle, which has a mass number of 0. The difference between 190 and 186 is 4, thus showing the emission of an alpha particle.

What is emitted when potassium -40 decays?
Potassium-40 decays by emitting a beta particle, which is an electron. This decay process transforms potassium-40 into calcium-40.
What particle is emitted when Na-20 decays to Ne-20?
When Na-20 decays to Ne-20, it emits a beta-minus particle, which is essentially an electron. This is because in beta-minus decay, a neutron is converted into a proton, releasing an electron and an antineutrino.
What particle is emitted when Pu-240 decays to U-236?
240Pu decays to 236U by emitting an alpha particle. You can tell this by looking at the difference in atomic mass. 240 minus 236 is 4, and that is the mass of an alpha particle. You can also tell this by looking at a chart of the nuclides. See the related link below for an example from Brookhaven National Laboratories.
What is emitted from the nucleus during beta decay?
During beta decay, a neutron is converted into a proton, releasing an electron (beta particle) and an antineutrino from the nucleus. The beta particle is emitted as the neutron decays into a proton, increasing the atomic number of the nucleus.
