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.
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.
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.
What happens to the amount of nitrogen14 as the carbon14 decays?
Remains the same
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 radium -226 decays to form radon -222 the radium nucleus emits?
When radium-226 decays to form radon-222, the radium nucleus emits a alpha particle.
When U-238 decays to th-234 what has been emitted?
When U-238 decays to Th-234, an alpha particle is emitted. An alpha particle consists of two protons and two neutrons, and is essentially a helium nucleus.
What particle does argon 39 atomic number 18 emit when it decays to potassium 39 atomic number 19?
