What element does promethium change into after emitting beta particles?
Isotopes of promethium decay to isotopes of neodymium.
Can atoms of radioactive element change into atoms of another element by emitting radiation?
Yes
How does an isotope of an element change during nuclear decay?
During nuclear decay, an isotope of an element changes by emitting radiation, such as alpha or beta particles, or gamma rays. This process results in the isotope transforming into a different element or a different isotope of the same element. The change is necessary to achieve a more stable configuration, typically by adjusting the number of protons and neutrons in the nucleus.
Summarize How radioactive decay can produce new element?
Radioactive decay occurs when an unstable atomic nucleus loses energy by emitting radiation, transforming into a more stable configuration. This process can involve the release of particles such as alpha particles, beta particles, or gamma rays. As a result, the original element may change into a different element; for example, when uranium-238 undergoes alpha decay, it transforms into thorium-234. Thus, radioactive decay not only results in the emission of radiation but also in the formation of new elements through nuclear transmutation.
What type of change does a neutron have?
A neutron does not have a charge; it is electrically neutral. However, it can undergo a type of change known as beta decay, in which it transforms into a proton by emitting an electron and an antineutrino. This process alters the atomic number of the element, effectively changing it into a different element.
Does nucleus changes its charge while emitting from beta and gamma particles simultaneously?
No, the nucleus does not change its overall charge when emitting beta and gamma particles simultaneously. Beta particles are high-energy electrons or positrons emitted during beta decay, whereas gamma particles are high-energy photons emitted during gamma decay. Both types of particles are neutral, so the overall charge of the nucleus remains the same.
Which particles that make up an atom are involved in nuclear reactions?
Protons, electrons, and neutrons are the subatomic particles that are involved in nuclear reactions.
The smallest part of an element that retains the elements characteristics?
The atom is the smallest particle of an element that retains it's characteristics. Sub-atomic particles such as protons, neutrons and electrons form the atom and it is the amount of each of these sub-atomic particles that make the element that element.
What does it mean when elements are unstable?
forming very strong bonds
What radioactive atoms spontaneously do?
Radioactive atoms spontaneously decay, emitting particles or energy in the process. This decay can result in the transformation of the atom into a different element or isotope to achieve a more stable state.
What happen to particles during a displacement reaction?
In a displacement reaction, one element replaces another element in a compound. The particles rearrange themselves into new molecules or compounds, resulting in the displacement of one element by another. This change can involve the transfer of electrons or bonding between atoms to form new substances.
When an atom beryllium-9 is bombarded by an alpha particles an atom of carbon-12 is produced and a neutron is emitted what kind of nuclear reaction has just occured?
The reaction described is a nuclear reaction known as a nuclear transmutation. When beryllium-9 is bombarded by an alpha particle (which is a helium-4 nucleus), it transforms into carbon-12 while emitting a neutron. This process involves the change of one element into another, demonstrating the principles of nuclear physics and the interaction between particles.
