- in alpha decay it loses a helium nucleus (2 protons, 2 neutrons)
- in beta decay a neutron converts to a proton and it ejects an electron and a neutrino
- in gamma decay an excited nuclear state relaxes and a gamma photon is emitted
- in "k-capture" an inner electron is eaten by the nucleus converting a proton to a neutron and it ejects a neutrino
there are also a few other mechanisms.
What else can I help you with?
What type of energy is released when one element decays into other element?
kinetic energy
What element creates Lead when it decays?
Thallium 204 turns into lead.
What is the first radioactive element that forms when uranium 238 decays?
The first radioactive element formed when uranium-238 decays is thorium-234. Uranium-238 undergoes alpha decay to form thorium-234.
How is the mass number of an element affected when it decays by ejecting an alpha partical?
The mass number of an element decreases by 4 when it decays by ejecting an alpha particle. This is because an alpha particle has a mass number of 4 and atomic number of 2. The atomic number of the element also decreases by 2.
What is the process by which an element slowly decays over time?
It is through radioactive decay that a quantity of an unstable element will decay over time. A material that is unstable will undergo this process, and the sample is said to be radioactive.
Why an element call radioactive?
it is unstable and decays to another element
When an isotope in the rock decays a new formed?

When an isotope in the rock decays a new what formed?

What type of energy is released when one element decays into other element?
kinetic energy
What is produced when a radioactive element decays?
When a radioactive element decays, it produces radiation in the form of alpha particles, beta particles, or gamma rays. This decay process can transform the element into a different element or a different isotope of the same element.
What is it called when an atom decays and become another element?
Radioactivity
What happens when radioactive element decays?
When a radioactive element decays, it releases energy in the form of radiation (such as alpha or beta particles). The decay changes the element into a different element or isotope, which may also be radioactive. This process continues until a stable non-radioactive element is formed.
What gas is produced when radium decays?
The extremely dangerous Radon (my favorite element).
What element creates Lead when it decays?
Thallium 204 turns into lead.
If uranium decays is it a chemical change?
No. It is a nuclear change, as the identity of the element changes.
What is the first radioactive element that forms when uranium 238 decays?
The first radioactive element formed when uranium-238 decays is thorium-234. Uranium-238 undergoes alpha decay to form thorium-234.
What happened to the part of the plutonium that is no longer ther?
Plutonium is a radioactive element that decays over time, transforming into other elements through a series of radioactive decays. When plutonium decays, it releases energy in the form of radiation and transforms into a different element. This process continues until the plutonium is no longer present.
