What type of decay does Am-241 undergo to become Np-237?
Americium-241 undergoes alpha decay to become Neptunium-237. During alpha decay, an alpha particle (two protons and two neutrons) is emitted, resulting in the conversion of Americium-241 to Neptunium-237.
How does radioactivity create new elements?
One way that elements decay is by alpha-emission. That means that the nucleus of the atom spews out alpha particles. An alpha particle is made of two protons and two neutrons, like a helium nucleus. Of course, once an alpha particle is emitted, the number of protons in the nucleus decreases, and the element changes with the number of protons.
The least energetic of the forms of radioactive decay is ______?
alpha decay
Does alpha decay always decreases the number of protons by an even number?
Yes, an alpha radiation particle is 2 protons and 2 neutrons so for every alpha particle emitted the radioactive nuclide loses 2 protons.
What is the kind of decay that's results in the formation of a different element?
Alpha decay is a kind of radioactive decay in which an alpha particle is emitted from an atom. An alpha particle consists of two protons and two neutrons. Therefore, when an atom of an element undergoes alpha decay, it loses two protons, which changes the atom from one element to another. This is because each different element is identified by the number of protons in its atomic nuclei.
What type of decay does fermium undergo?
Fermium undergoes primarily alpha decay, where it emits an alpha particle consisting of two protons and two neutrons. This process reduces the atomic number by 2 and the atomic mass by 4.
Why doesn't alpha decay occur for hydrogen?
Alpha decay is a process where an atom emits an alpha particle, which is a helium nucleus consisting of 2 protons and 2 neutrons. Since a hydrogen atom only has one proton, it cannot undergo alpha decay as it lacks the necessary particle combination to release an alpha particle.
What type of decay does Am-241 undergo to become Np-237?
Americium-241 undergoes alpha decay to become Neptunium-237. During alpha decay, an alpha particle (two protons and two neutrons) is emitted, resulting in the conversion of Americium-241 to Neptunium-237.
What are the elements of alpha decay?
Alpha particle is composed of two protons and two neutrons (equivalent to He nucleus). So the parent decaying by alpha decay results in a daughter having atomic number less by two and mass number less by four.
what are the additional two elements and nucleon numbers in the decay chain if there were two more alpha decay steps after lead-206.?

What type of nuclear decay does Uranium undergo?
Uranium has a different decay chain/series for its different isotopes. Uranium 238 for example first decays to thorium 234 through alpha decay while U235 alpha decays to thorium 231. Both have different half lifes which can be found on a natural decay series chart for the said element. The thorium in either case then beta decays to another element.
What is the type of radioactive decay in which positive particles are given off?
Alpha decay is the type of radioactive decay in which positive particles, specifically alpha particles, are emitted. These alpha particles consist of two protons and two neutrons bound together, giving them a positive charge.
Alpha and beta decay emit what?
Alpha decay emits an alpha particle, which consists of two protons and two neutrons. Beta decay emits either an electron (beta minus decay) or a positron (beta plus decay).
What type of radioactive decay resulted in uranium-238 becoming thorium-234 and how do you know?
This is alpha decay.If you notice carefully, uranium has 238 atomic wt. and on decaying becomes thorium with atomic wt. of 234. hence it lost atomic wt. of 4. He, which is released in alpha decay, has atomic no. of 4. Hence, if uranium decayed into Helium and Thorium, it will undergo Alpha Decay
Which nuclear reaction is classified as alpha decay?
The equation for the alpha decay of 210Po is:84210Po --> 82206Pb + 24He where He represents the alpha particle, which can also be viewed as a Helium nucleus.
In alpha decay is the atomic number of the daughter nucleus equal to the atomic number of the isotope undergoing decay?
No, in alpha decay the atomic number of the daughter nucleus is decreased by 2 and the mass number is decreased by 4 compared to the isotope undergoing decay. This is because an alpha particle (helium nucleus) is emitted during alpha decay, resulting in a new daughter nucleus with a lower atomic and mass number.
How does radioactivity create new elements?
One way that elements decay is by alpha-emission. That means that the nucleus of the atom spews out alpha particles. An alpha particle is made of two protons and two neutrons, like a helium nucleus. Of course, once an alpha particle is emitted, the number of protons in the nucleus decreases, and the element changes with the number of protons.
