The weak nuclear force is responsible for all particle decay. In a neutron, there are two down (d) and one up (u) quars with charges of -1/3 and +2/3, respectively. In a proton, there are two up and one down quark. The configuation looks like this:
N: udd
P: uud
One of the down quarks in the neutron changes into an up quark (via the W- particle) and an electron. The neutron is now a proton.

What is the charge of the emitted particle in alpha decay?
In alpha decay, the emitted particle has a charge of 2.
What are the particles emitted during radioactive decay with their mass and charge?
alpha: mass 4, charge +2beta: mass ~1/1800, charge -1gamma: mass 0, charge 0
When a nucleus undergoes alpha decay the daughter element always has less charge than the parent?
No, the daughter element after alpha decay has less atomic number than the parent (reducing charge), but the total charge (protons) in the nucleus remains the same. The daughter element gains stability by emitting an alpha particle, which consists of two protons and two neutrons.
Order gamma decay beta decay and alpha deacy form weakest to strongest?
From weakest to strongest decay, the order is: Gamma decay - involves the emission of high-energy photons. Beta decay - involves the emission of beta particles (electrons or positrons). Alpha decay - involves the emission of alpha particles (helium nuclei).
Do radioactive emissions have a charge?
Depends on what type of radioactive decay you are talking about. Beta decay (electron or positron) will have a charge, while alpha decay will not. Beta decay can either be positron decay or electron decay. Positron will result in the parent to have the same atomic mass but a different atomic number. The atomic number will be one less than that of the parent. Meaning one proton will decay into a neutron and a positron, which is a positively charged particle. Electron decay results in the parent gaining a proton while the atomic mass stays the same. A neutron decays into a proton and an electron and the electron is emitted with a negative charge. Alpha decay, however, results in the emission of a neutral helium particle. Gamma decay results in the same parent with no loss of charge or atomic number and gives off a high energy photon called a gamma particle.
What is the charge of the emitted particle in alpha decay?
In alpha decay, the emitted particle has a charge of 2.
What is the type of radioactive decay in which positive particles are given off?
Alpha decay is the type of radioactive decay in which positive particles, specifically alpha particles, are emitted. These alpha particles consist of two protons and two neutrons bound together, giving them a positive charge.
What correctly describes the charge of beta particles and alpha particles?
Beta particles have a negative charge, while alpha particles have a positive charge. Beta particles are electrons or positrons, while alpha particles are helium nuclei consisting of two protons and two neutrons.
What are the particles emitted during radioactive decay with their mass and charge?
alpha: mass 4, charge +2beta: mass ~1/1800, charge -1gamma: mass 0, charge 0
When a nucleus undergoes alpha decay the daughter element always has less charge than the parent?
No, the daughter element after alpha decay has less atomic number than the parent (reducing charge), but the total charge (protons) in the nucleus remains the same. The daughter element gains stability by emitting an alpha particle, which consists of two protons and two neutrons.
What do alpha particles contain?
They are Helium nucleii so basically 2 protons and 2 neutrons
Is alpha decay the same as alpha radiation?
No. Decay is the process, radiation is the product.
Order gamma decay beta decay and alpha deacy form weakest to strongest?

What type of decay is 235 92U---4 2 He plus 231 90Th?
The type of decay for this process is alpha decay. In alpha decay, a heavy nucleus emits an alpha particle (helium-4 nucleus) to transform into a new element with a lower atomic number.
Alpha and beta decay emit what?
Alpha decay emits an alpha particle, which consists of two protons and two neutrons. Beta decay emits either an electron (beta minus decay) or a positron (beta plus decay).
What is the heaviest of the forms of radioactive decay is?
I'm pretty sure its alpha.
