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.
When U-238 decays to th-234 what has been emitted?
An Alpha particle, and associated gamma radiation from the excited nucleus.
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
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.
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.
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 particle does argon-39 atomic number 18 emit when it decays to potassium-39 atomic number 19?
electron or beta particle

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.
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?
An Alpha particle, and associated gamma radiation from the excited nucleus.

When a beta particle is ejected from a nucleus the nucleus then has greater?
When a beta particle is ejected from a nucleus, the nucleus gains one unit of positive charge as it transforms a neutron into a proton. This results in an increase in the atomic number of the atom while the mass number remains the same.
What happens when californium 251 decays into curium 247?
When californium-251 decays into curium-247, it undergoes alpha decay, releasing an alpha particle (helium nucleus) in the process. This results in the transformation of the nucleus to curium-247 with a simultaneous decrease in atomic number and mass number.
