After an element's nucleus decays, it becomes one or more different elements. The type of decay determines what the new element(s) will be. The type of decay the nucleus of an element will undergo depends on the particular isotope of the particular element in question. For example, alpha decay results in an new element which has 2 less protons and 2 less neutrons (decrease in atomic number of 2 and decrease in mass number of 4). Fission results in an element splitting into two new elements of various sizes, accompanied by the release of other random particles. The two new "daughter" element's masses plus the masses of the other released particles will add up (approximately) to the mass of the original element. There are many other types of decay which produce different decay products.

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 the daughter nucleus produced wnhen 213Bi undergoes alpha decay?

How can an atom emit a proton?
An atom cannot emit a proton. Protons are found within the nucleus of an atom and do not naturally emit from an atom. The process where protons are emitted from a nucleus is called proton emission and typically occurs in nuclear reactions or decays in radioactive isotopes.
Why alpha and beta decay will change the nucleus and produce new element?
Alpha radiation is when the nucleus of an unstable element releases an alpha particle (two protons and two neutrons; the equivalent of the nucleus of a helium atom)due to the weak nuclear force. The resulting atom is now a different element because the number of protons it has determines which element it is. Beta radiation (β− ) is when a neutron in an unstable atom with an excess of neutrons turns into a proton because of a virtual W− boson, one of the particles that carries the weak force. This boson then decays into an electron and an electron type antineutrino. Another type of beta radiation (β+ ) is the same as the previous type except that a proton decays into a neutron and a W+ boson decays into a positron (electron antiparticle) and an electron type neutrino instead. Beta radiation changes the number of protons in a nucleus and therefore the type of element.
What is the definition of a radioisotpoe?
A radioisotope is an unstable form of an element that releases radiation as it decays into a more stable form. Radioisotopes are used in various applications, such as medical imaging, cancer treatment, and scientific research.
Which of the decays doesnt affect the nucleus?
Electromagnetic, as the nucleus has no charge
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.
When does decay occur?
Radioactive decay happens in an unstable isotope of a given element, as the isotope decays radiation is given off. As for when exactly, the decay of a nucleus is spontaneous and random so averages are used, these averages are different for different isotopes, but are measured as the "half life" (the time it takes for half the nucleus to decay).
When an element decays what does it lose?
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 neutrinoin gamma decay an excited nuclear state relaxes and a gamma photon is emittedin "k-capture" an inner electron is eaten by the nucleus converting a proton to a neutron and it ejects a neutrinothere are also a few other mechanisms.
Are the alpha particle and helium nucleus the same thing?
Yes and no, alpha particles are a form or radiation (a helium nucleus), they are emitted from an unstable radioactive element which decays (and turns into some lighter element) by emitting the alpha particle. This form of decay is called alpha decay.
Why an element call radioactive?
it is unstable and decays to another element
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.
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.
If The parent element decays by beta decay. Which daughter element will form?
If the parent element undergoes beta decay, it will transform into a daughter element with an atomic number that is one greater than the parent element. This occurs when a neutron in the nucleus is transformed into a proton, releasing an electron (beta particle) and an antineutrino.
When C-14 beta decays the daughter nucleus is?

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