What particles has the same mass as an electron but a positive charge and is sometimes emitted from the nucleus during radioactive decay?
A positron is a particle with the same mass as an electron but a positive charge. It is the antimatter counterpart of an electron and can be emitted from the nucleus during some types of radioactive decay processes, such as beta plus decay.
What are the different types of decay that can occur in various materials?
There are several types of decay that can occur in materials, including physical decay (such as wear and tear), chemical decay (such as rusting or corrosion), and biological decay (such as rotting or decomposition).
What are the different types of radioactive decay and how do they differ from each other?
There are three main types of radioactive decay: alpha decay, beta decay, and gamma decay. Alpha decay involves the emission of an alpha particle, which is a helium nucleus consisting of two protons and two neutrons. This type of decay reduces the atomic number of the nucleus by 2 and the mass number by 4. Beta decay involves the emission of a beta particle, which can be either an electron (beta-minus decay) or a positron (beta-plus decay). Beta decay changes the atomic number of the nucleus by 1 but does not significantly affect the mass number. Gamma decay involves the emission of gamma rays, which are high-energy photons. Gamma decay does not change the atomic number or mass number of the nucleus but helps the nucleus reach a more stable energy state. These types of decay differ in the particles emitted and the changes they cause to the nucleus.
The least energetic of the forms of radioactive decay is ______?
alpha decay
Do diamonds decay over time?
No, diamonds do not decay over time. They are one of the hardest substances on Earth and are extremely resistant to decay or deterioration.
What two radioisotopes have the same decay mode?

What is the decay mode for 129xe that decays to 129I?
Beta
How to predict the mode of decay in radioactive substances?
To predict the mode of decay in radioactive substances, scientists use the concept of nuclear stability and the ratio of protons to neutrons in the nucleus. By analyzing these factors, they can determine whether a radioactive substance will decay through alpha, beta, or gamma decay.
Compared to the half life and decay mode of the nuclide 90sr the nuclide 226ra has?
Compared to the half-life and decay mode of the nuclide (^{90}\text{Sr}), the nuclide (^{226}\text{Ra}) has a significantly longer half-life and a different decay mode. (^{90}\text{Sr}) has a half-life of about 28.8 years and primarily decays via beta decay to (^{90}\text{Y}). In contrast, (^{226}\text{Ra}) has a half-life of about 1,600 years and decays primarily through alpha decay to (^{222}\text{Rn}). This means that (^{226}\text{Ra}) is more stable and persists longer in the environment compared to (^{90}\text{Sr}).
Why there's not a formula for beta decay?
There certainly is a formula for beta decay. You just need to know the parent nuclide and the beta mode, beta- or beta+. See the related question below which answers this quite well.
What is the correct order of nuclear decay mode for the changes from U-238 to U-234?
The correct order of nuclear decay mode for the changes from U-238 to U-234 is alpha decay followed by beta decay. In alpha decay, the nucleus emits an alpha particle, reducing its atomic number by 2 and mass number by 4, resulting in Th-234. This is followed by beta decay, where a neutron is converted into a proton, producing U-234.
How would you write a nuclear equation for the most likely mode of decay for the unstable nuclide Kr-74?
Krypton-74 will most likely undergo beta decay, and the type of beta decay an observer will encounter will be beta plus decay. A proton in the nucleus will undergo a change and become a neutron, and a positron (e+) and an antineutrino (ve) will emerge from the reaction. The krypton-74 atom will transmute into a bromine-74 atom. The equation will look something like this: 3674Kr => 3574Br + e+ + ve
How can you say that radioactive decay is random unless you know that the nuclides are identical in the first place?
Radioactive decay is a random event. But we can assess it by statistical analysis of a large number of decay events across time for a given radionuclide. Standard stastical analysis ideas apply. The way we know that it is the radionuclide we specify is that we refine the sample chemically. Then we look at the decay mode. If it is a situation where there is particle emission, we can identify the particle and the energy it comes out at. If its electromagnetic, we can specify an energy associated with the photon. The mode of decay and the energy cast off are the ways we can insure our "count" of the decay events specifically targets the radionuclide we are investigating. That and the applied chemistry we specified to clean up the sample. We're good at this radioactive decay thing. We can count even a very few decay events, and do so accurately across time (though more is better). And because we've done our homework as regards type of decay and energies, we know what it is that is decaying, and how long it is taking to decay. We can arrive at a half-life for a given radionuclide. A link can be found below.
What do you know about an isotope?
Isotopes have same atomic number. They have different mass numbers. Their physical properties are different.
What particles has the same mass as an electron but a positive charge and is sometimes emitted from the nucleus during radioactive decay?
A positron is a particle with the same mass as an electron but a positive charge. It is the antimatter counterpart of an electron and can be emitted from the nucleus during some types of radioactive decay processes, such as beta plus decay.
What are the four types of nuclear decay in order?
The four types of nuclear decay are alpha decay, beta decay, gamma decay, and neutron decay. Alpha decay involves the emission of an alpha particle, beta decay involves the emission of beta particles (either electrons or positrons), gamma decay involves the emission of gamma rays, and neutron decay involves the emission of a neutron.
What does ununhexium decay into?
The decay products of ununhexium (after alpha decay) are isotopes of ununquadium.
