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.
What particle does argon 39 atomic number 18 emit when it decays to potassium 39 atomic number 19?
An electron - also referred to as a beta particle.
When radium-226 (atomic number 88) decays by emitting an alpha particle it becomes .?
?
When thorium decays by emmitting an alpha particle what is the atomic number of the resulting nucleus?
88Ra, Radium
Is radium identical to an alpha particle?
No. Radium is a heavy metal, atomic number 88 (with 88 protons). An alpha particle is a helium nucleus, atomic number 2. Radium decays by each atom emitting an alpha particle, becoming Radon gas, atomic nubmer 86.
When radium-226 decays to form radon-222 the radium nucleus emits a?
When Radium-226 decays to form Radon-222, the Radium nucleus emits an alpha particle. The atomic number goes down by 2, and the mass number goes down by 4, matching the atomic number and mass number of the alpha particle.
When carbon-14 decays and emits a beta particle what is the atomic mass on the new nucleus?
Atomic number goes up by 1 and Mass stays the same
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 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.
Which particle is emitted when an atom OF 85Kr spontaneously decays?
a beta particle
What happens when U-235 emits a beta particle?
beta decay results from the transformation of a neutron in the nucleus to a proton (+ charge) and an electron (beta particle). The proton remains in the nucleus increasing the atomic number by one (mass number remains the same) while the electron is emitted as a beta particle. So, U-235 of atomic number 92 changes to Neptunium with atomic number 93. However, to my knowledge, U-235 decays by gamma not beta. U-236 decays by beta to Neptunium-236.
The nuclear reaction for the emission of gamma particle from cobalt 60?
Cobalt-60m decays by emitting a gamma particle. This changes neither the atomic number nor the isotope number, since no nucleons are lost. The gamma particle has an energy of 58.59 keV. The resulting atom is Cobalt-60.
