NovaNet: A beta particle is simply a high speed electron.
An electron emitted by a neutron as it becomes a proton.
When a nucleus undergoes beta radiation, a neutron breaks a part, splitting into a proton and a electron. The proton changes the atomic number, adding a +1 to it.
Yes and no, alpha particles are a form or radiation (a helium nucleus), they are emitted from an unstable radioactive element which decays (and turns into some lighter element) by emitting the alpha particle. This form of decay is called alpha decay.
alpha particle, He nucleus
An alpha particle is a helium nucleus, which consists of 2 protons and 2 neutrons. When an unstable nucleus emits an alpha particle, it loses 2 protons, which means its atomic number will be reduced by 2.
The atomic number decreases by one for each beta particle
When U-238 decays to Th-234, an alpha particle is emitted. An alpha particle consists of two protons and two neutrons, and is essentially a helium nucleus.
Positrons are emitted from proton-rich radioactive during positive beta-decay.
It is negative beta particle emitted by a uranium nucleus and converting it to neptunium nucleus.
Nucleus
In short, alpha radiation occurs when an unstable nucleus emits 2 protons and 2 neutrons from it's nucleus. This means that the atomic number decreases by 2 and the nucleon number decreases by 4.
Gamma rays.
Yes and no, alpha particles are a form or radiation (a helium nucleus), they are emitted from an unstable radioactive element which decays (and turns into some lighter element) by emitting the alpha particle. This form of decay is called alpha decay.
Yes. When an atom emits a Bita particle, actually its the degradation of a neutral particle, i.e a neutron, which forms a proton and an electron. Since no electron can exist inside a nucleus, so it is emitted out as a bita particle, but the proton stays inside the nucleus, thereby increasing its atomic number by 1.
alpha particle, He nucleus
An alpha particle is a helium nucleus, which consists of 2 protons and 2 neutrons. When an unstable nucleus emits an alpha particle, it loses 2 protons, which means its atomic number will be reduced by 2.
Particles or electromagnetic radiation are emitted.
beta particle
The nucleus of a helium atom is called an alpha particle. The electromagnetic waves emitted by a nucleus are called gamma rays.
