In beta- decay, a neutron is converted into a proton, and an electron and an electron antineutrino is emitted. More fundamentally, a down quark is converted into an up quark by the emission of a W- boson. The quark conversion is part of the neutron becoming a proton, and the W- boson subsequently decays into the electron and electron antineutrino.
In beta+ decay, a proton is converted into a neutron with the addition of energy, and a positron and an electron neutrino is emitted. More fundamentally, an up quark is converted into a down quark, causing the emission of the electron and electron antineutrino. If the beta+ decay also involves K capture, which is the capture of a K shell electron into the nucleus, then there will be subsequent realignment of the electron shells and emission of photons of various energies (x-ray) as the electrons come back to ground state.

∙ 14y agoHelium. Well i do't know about Biology but in chemistry alpha decay leads to a particle decaying and in the process losing 2 protons and 2 neutrons.
which has a symbol of 42 which is Helium (2) 42He so for example:
168O ---> 42He + 126C (just an example of the concept) //////////////////////////////////////////////////////////// We're looking for an answer between A. the heavier elements B. the lighter elements C. the white elements D. the stable elements Your welcome platoweb people... you know who you are.

∙ 14y agoHelium nucleii (He2+), also known as alpha particles.
When an atom undergoes alpha decay the nucleus emits two protons and two neutrons. This is called an alpha particle or a (He+2, read as plus 2 helium). The reason it is plus 2 is because the helium (alpha particle) gets ejected without any electrons. Typically the alpha particle is denoted by the Greek letter alpha.

∙ 12y agoThe particles released during alpha decay are called alpha particles. They are helium nuclei, and their symbol is 24He2+.
Additionally, depending on the situation, the release of the alpha particle can leave the nucleus and/or the electron cloud in a excited state. If this happens, the return to ground state is accompanied by the release of a photon with gamma energy (nucleus) or x-ray energy (electron cloud), sometimes, multiple photons.

What type of decay is involved when polonium -214 decays into lead -210?
It is alpha decay. In the process, an alpha particle(He2+) is released. So, it is called alpha decay.
High-energy light waves that are released from a radioactive nucleus during alpha decay and beta decay?
Gamma rays, which are photons with a certain energy step change, are emitted from the nucleus when the nucleus is returned from an excited state back down to ground state, as often occurs during alpha and beta decay.
Where could one locate Alpha particles?
Alpha particles are most commonly found when alpha decay occurs. An alpha particle is emitted during alpha decay. Further information about alpha particles can be found on the Wikipedia website.
One kind of radiation not released by radioactive decay is .?
alpha particles
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?
gamma decay beta decay alpha decay
Is alpha decay the same as alpha radiation?
No. Decay is the process, radiation is the product.
Do element identities reamin the same or change during nuclear decay?
That depends on the nuclear decay type. For gamma decay, the identity does NOT change, but for alpha and beta, it does.
What is the type of radioactive decay in which positive particles are given off?
It's called alpha-decay. The two protons and two neutrons are removed in the form of alpha particles, or helium nuclei.
What is the product of radioactive decay called?
Product of radioactive decay 42He is an alpha particle
The particle with two protons and two neutrons ejected during decay?
Alpha particle
What is a particle with two neutrons and two protons ejected during decay?
