Which particle is emitted from a hydrogen-3 nucleus when it undergoes radioactive decay?
beta, aka an electron.
What are the properties of radioactive decay?
Radioactive decay has the following properties: 1. No element can completely decay. 2. The number of atoms decaying in a particular period is proportional to the number of atoms present in the beginning of that period. 3. Estimate of radioactive decay can be made by half life and decay constant of a radioactive element.
What are 3 terms that mean radioactive decay?
Dental Caries is the scientific name for 'tooth decay.'
What accompanies the decay of an unstable nucleus?
Radioactive decay.There are 3 types of radiation:1. Alpha particles (helium nucleus)2. Beta particles (electrons)3. Gamma rays (electromagnetic radiation)
All substances that naturally undergo radioactive decay do so until they finally become a stable isotope of one particular element what is the element?
The decay of radioactive substances follows a decay chain that will sooner or later result in the appearance of a stable isotope of lead. There is an exception for the atoms of a few substances that have undergone decay by spontaneous fission.
What is the lightest element that can undergo radioactive decay and what type of decay occurs in that element?
The lightest "element" that can undergo radioactive decay is the isotope hydrogen-3, which undergoes beta decay. The lightest element with no radioactively stable isotopes is technetium, and its isotopes have different modes of decay.
Is tritium on the periodic table?
The isotope of hydrogen we call tritium is radioactive because all atoms of it have an unstable nucleus. Tritium, which is hydrogen-3, has a single proton in its nucleus (as you'd expect), and has two neutrons there as well. This combination of nucleons is not stable, and it will eventually decay (with a 12.32 year half-life). Said another way, the nuclear arrangement of a proton and two neutrons is not a stable one, so atoms of this isotope of hydrogen will be radioactive and will eventually decay. When any atom is "created" by fusion or other means (including nuclear decay), the nucleons (the protons and neutrons that make up its nucleus) have to "make a deal" as to how they are going to get along in the tiny volume of space that the nucleus occupies. Some arrangements of protons and neutrons just "aren't right" and are unstable, and this gives rise to characterizing the isotope as being radioactive. Tritium (H-3) is one such isotope.
What is a by product of radioactive decay?
The 3 things that can happen during radioactive decay is the 3 parts of decay: Alpha decay, Beta decay, and Gamma decay. In alpha decay, which is the weakest part of decay, it has a positive helium neuclus(2 protons and 2 neutrons), and the particles will burn your skin, but can be easily stopped by a peice of paper. This is the most ionising as the helium nucleus can take electrons from other atoms and make them unstable. This can give rise to cancers as it distorts cells. In Beta decay (an electron or a positron) is emitted. In the case of electron emission, it is referred to as "beta minus" (β−). It can be stopped by 3mm of aluminum. Gamma decay, which is the strongest, can only be stopped by 3cm of lead. It has electromagnetic waves, it contains the most energy, and therefore is the most penetrating, but normally it just passes straight through the human body. Radioactive decay can be very harmful, and its best to stay away. This question has been anwsered by Rae-Ann Salisbury.
What is a form of radioactive decay?
There are 3 forms:Alpha, ejection of a helium nucleus (2 protons and 2 neutrons)Beta, this has 3 variants itself but all involve the same processes: -Beta, +Beta, and K captureGamma, ejection of a very high energy photonThe 3 variants of Beta decay are: -Beta, ejection of an electron and a neutrino, while a neutron in the nucleus becomes a proton+Beta, ejection of a positron and a neutrino, while a proton in the nucleus becomes a neutronK capture, capture of an electron from the innermost shell (K shell) and ejection of a neutrino, while a proton in the nucleus becomes a neutron
What is the nuclear decay equation for hydrogen-hydrogen?
The only hydrogen isotope that undergoes any type of radioactive decay is tritium (hydrogen-3), it undergoes beta decay to become helium-3. If that's not what you were asking about, I'm confused by your question.
A fast moving electron that is given off as a nuclear radiation is called?
Ok if what your looking for is an electron released from radioactive decay, it's a beta particle, which is created in beta decay =]In beta decay, a neutron in the nucleus spontaneously turns into a proton, an electron, and a third particle called an antineutrino. The nucleus ejects the electron and antineutrino, while the proton remains in the nucleus. The ejected electron is referred to as a beta particle. The nucleus loses one neutron and gains one proton. For example, a hydrogen-3 atom undergoing beta decay becomes a helium-3 atom.So simply, its a beta particle. But I also gave you a science explanation.Feel proud man =D
How radioactive are gamma rays?
They have a radiation weighting factor of 1. This is used in equivalent dose (H=DWr) As a use for comparison: - Alpha particles = 20 - Beta particles = 1 - Fast Neutrons = 10 - Slow Neutrons = 3
