Which radioisotope emits an alpha particle?
For example isotopes U-234, U-235, U-238.
What changes take place in the nucleus when an alpha particle is emitted?
In short, alpha radiation occurs when an unstable nucleus emits 2 protons and 2 neutrons from it's nucleus. This means that the atomic number decreases by 2 and the nucleon number decreases by 4.
What element does thorium-230 decay when it emits an alpha particle?
226 88Ra
What happens to the mass number of a nucleus when it emits an electron?
When a nucleus emits a beta particle (electron) it is a result of neutron decay. This decay will also release an antineutrino and a proton is left which increases the atomic mass by one thereby changing the element.
What element does thorium 230 decay when it emits an alpha particle?
This isotope is radium-226.
Which radioisotope emits an alpha particle?
For example isotopes U-234, U-235, U-238.
How does the composition of an atom change when it emits a beta particle?
When a nucleus emits a beta particle, it loses one of its neutrons and gains one proton. Hence, it's mass and atomic number remain the same but its charge and What_happens_to_a_nucleus_when_it_emits_a_beta_particlenumber is increased by +1.
Which is not a characteristic of energy?
the answer is humidity
What happens to the number of protons when U-238 emits an alpha particle?
The number of protons decreases by 2.
What happens to an isotope during radioactive?
That depends on the specific radioisotope. For instance, uranium 238 emits an alpha particle during radioactive decay, reducing the number of protons and neutrons in the nucleus by 2 each and producing thorium 234. On the other hand, carbon 14 emits a beta particle (an electron) during radioactive decay, decreasing the number of neutrons and increasing the number of protons by 1 each and producing nitrogen 14. There are quite a few other examples with different changes depending on the type of radioactive decay.

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 the change in the atomic number when the atom emits an alpha particle?
The atomic number will decrease by 2, the number of protons in the emitted alpha particle. An alpha particle is a helium-4 nuclei with two protons and two neutrons.
What happens to radioactive isotopes during radioactive decay?
That depends on the specific radioisotope. For instance, uranium 238 emits an alpha particle during radioactive decay, reducing the number of protons and neutrons in the nucleus by 2 each and producing thorium 234. On the other hand, carbon 14 emits a beta particle (an electron) during radioactive decay, decreasing the number of neutrons and increasing the number of protons by 1 each and producing nitrogen 14. There are quite a few other examples with different changes depending on the type of radioactive decay.
When thorium emits beta particle the resulting nucleus has a atomic number?
The resulting element is protactinium, atomic number 91.
If bismuth-213 emits an alpha particle what is it?
bismuth will contain 81 protons turning into Thallium with an atomic number of 81. If it emits a beta particle it doesn't change its still bismuth, only it become more energetic.
If a radioactive nucleus with an atomic number of 88 emits an alpha particle what will the atomic number of the new nucleus be?
Two less, since the alpha particle takes away two protons.
