What is the difference between domestic and industrial waste?
Domestic waste are products that are liable to decay while industrial waste is any material that is rendered futile after a manufacturing process
What are the characteristic of rubber tire or other things that not decay?
Things that don't decay (or that don't decay quickly) are difficult to digest, for bacteria.
What two things do radioactive atoms give off when they decay?
Radioactive atoms can give off several different particles. There are three different "types" of radiation, beta, gamma, and alpha. Beta decays which give off electrons/positrons as well as gamma rays (usually). Gamma emmitters are generally meta stable particles that omit a gamma ray in order to stabilize the nuclears, and their are alpha decays which eject a alpha particle (a helium nucleus). On rarer occasions radioactive particles can also be classified as neutron emitters.
What is to decay or decompose?
something
When a nucleus undergoes radioactive decay its new mass number is?
It depends. If the decay contains a particle with mass, then the nucleus' mass number must decrease. If the decay involves the emission of a massless particle (like a gamma photon), then the mass number is unchanged. If the reaction (not technically a decay) involves the nucleus absorbing a particle with mass (like U-235 absorbing a neutron in a fission chain reaction) then it is a transmutation and not a natural decay. The mass number must increase.
How is the radioactive decay of an element used to determine the age of a rock layers?
Radioactivity, and more specifically, radioactive decay, involves the spontaneous expulsion of a proton from the nucleus of an atom. It is important to note that this process is random and spontaneous; in other words, we can never know exactly when an element will decay.
Which equation represents a spontaneous nuclear decay?
All nuclear decay is spontaneous.
What is meant by the term random decay?
Random decay refers to the spontaneous breakdown or disintegration of atomic nuclei without external influence, leading to the emission of radiation such as alpha, beta, or gamma particles. This process occurs unpredictably and is governed by the probabilistic nature of quantum mechanics, resulting in an exponential decay of radioactive isotopes over time.
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).
What is non radioactive decay?
Radioactive decay is the spontaneous change or disintegration of an unstable atomic nucleus as it transforms itself to lose energy. It does this by the release of either particulate radiation or electromagnetic radiation, or both. This atomic event is random and cannot be predicted, but by applying statistical principles to large numbers of a given radionuclide, an "average" decay time can be found, and we have the half-life. There are several different types of radioactive decay. They range from spontaneous fission to alpha decay, beta decay and a couple of others. The spontaneous breakdown of a nucleus
Is the best definition of radioactive decay?
Radioactive decay is the spontaneous breakdown of a nucleus into smaller parts.
What is spontaneous emission of radiation from an element?
This could have many names such as 'decay', 'radioactive decay', or 'radiation.
What is the best definition of radioactive decay?
Radioactive decay is the spontaneous breakdown of a nucleus into smaller parts.
What is The spontaneous decay of an atom is called?
Nuclear decay.Different types of nuclear decay include:Alpha Decay, where the nucleus ejects a charged particle made of protons and neutrons.Beta Decay, where a neutron turns into a proton, a Beta particle (an electron or positron) and a neutrino.Gamma radiation can also be emitted in these processes.
Radioactivity is caused due to what?
spontaneous decay of unstable atomic nuclei.
Is nuclear decay spontaneous or artificial?
Matter can be made to undergo nuclear decay in reactors, but it is a process that occurs spontaneously in nature.
What is the difference between nuclear decay and nuclear transformation reactions?
Nuclear decay is the spontaneous process where an unstable nucleus emits particles or energy to become more stable. Nuclear transformation reactions involve bombarding a nucleus with particles to alter its composition or create new nuclei. Decay is a natural process, while transformation reactions are induced.
