When an unstable nucleus produces an alpha particle by how many units does the atomic number of the nucleus change?
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.
Are the alpha particle and helium nucleus the same thing?
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.
When an unstable nucleus produces an beta particle by how many units does the atomic number of the nucleus change?
The atomic number decreases by one for each beta particle
When U-238 decays to th-234 what has been emitted?
An Alpha particle, and associated gamma radiation from the excited nucleus.
How beta particles are emitted from nuclei as there are no electrons in nucleas of an atom than from where beta rays are emmited?
nucleus is a very complicated region and we known little about thattheoretically a neutron is broken down to a proton and a beta particle during radioactivity so with in nucleus beta particle is a part of neutron.

What type of particle is emitted when a U-235 decays to Np-235?
It is negative beta particle emitted by a uranium nucleus and converting it to neptunium nucleus.
Nuclear radiation refers to charged particles or energy emitted by an unstable what?
Nucleus
A penetrating ray of energy emitted by an unstable nucleus?
Gamma rays.
Are the alpha particle and helium nucleus the same thing?
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.
When an unstable nucleus emits a beta particle is the atomic number increased by one unit?
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.
What changes take place in the nucleus when an alpha particle is emitted?
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.
What kind of charge does the particle emitted from the nucleus during betta - decay have?
The particle emitted during beta- decay is an electron, therefore it has a negative charge.
What is emitted from the nucleus during beta decay?
During beta decay, a neutron is converted into a proton, releasing an electron (beta particle) and an antineutrino from the nucleus. The beta particle is emitted as the neutron decays into a proton, increasing the atomic number of the nucleus.
What is a negative electron emitted from the nucleus of an atom at high speed?
beta particle
Is a delta particle a fast moving electron given off by a nucleus during radioactive decay?
No, a delta particle is not a fast moving electron given off by a nucleus during radioactive decay. The electron described here is a beta particle, and specifically a beta minus particle. It is given off in (no surprise) beta minus decay. A link to a related question can be found below.
