A fast moving electron given off as part of a nuclear reactions is a beta particle. Also, anti-electrons, known as positrons, are beta particles. Electrons are involved in beta- decay, along with anti-neutrinos; and positrons are involved in beta+ decay, along with neutrinos.

When an electron is ejected from the surface what type of energy does the electron possess?
It is moving, so it has kinetic energy.
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.
How radiation takes place?
Naturally occurring radiation is because of the instability of the nuclei of some atoms. The nucleus of an atom contains protons and neutrons, or positive and neutral particles. These positive particles are constantly repelling each other, but bind energy holds the nucleus together. The particles in the nucleus are not stationary, but are moving around. This can sometimes cause the instability to increase and 'throw' out some of the particles. This is radioactive decay.
Using heisenberg's uncertainity principle prove the non existence of the electron inside the nucleus?
The Heseinberg's Uncertainty Principle states that you cannot know the position and momentum of a particle simultaneously. More rigorously stated, the product of the uncertainty of the position of a particle (Δx) and the uncertainty of its momentum (Δp) must be greater than a specified value: ∆x∆p ≥ (h/4π) Now, as the electron approaches the nucleus, it's uncertainty in position decreases (if the electron is 10nm away from the nucleus, it could be anywhere within a spherical shell of radius 10nm, but if the electron is only 0.1nm away from the nucleus, that area is greatly reduced). According to the Heisenberg uncertainty principle, if you decrease the uncertainty of the electrons position, the uncertainty in its momentum must increase. This increased momentum uncertainty means that the electron will be moving away from the nucleus faster, on average. Put another way, if we do know that at one instant, that the electron is right on top of the nucleus, we lose all information about where the electron will be at the next instant. It could stay at the nucleus, it could be slightly to the left or to the right, or it could very likely be very far away from the nucleus. Therefore, because of the uncertainty principle it is impossible for the electron to fall into the nucleus and stay in the nucleus. In essence, the uncertainty principle causes a sort of quantum repulsion that keeps electrons from being too tightly localized near the nucleus.
Can exact path of a moving electron be predicted?
no
When an electron is ejected from the surface what type of energy does the electron possess?
It is moving, so it has kinetic energy.
A fast moving electron that is given off as a nuclear radiation is called?
Ok if what your looking for is an electron released from radioactive decay, it's a beta particle, which is created in beta decay =]In beta decay, a neutron in the nucleus spontaneously turns into a proton, an electron, and a third particle called an antineutrino. The nucleus ejects the electron and antineutrino, while the proton remains in the nucleus. The ejected electron is referred to as a beta particle. The nucleus loses one neutron and gains one proton. For example, a hydrogen-3 atom undergoing beta decay becomes a helium-3 atom.So simply, its a beta particle. But I also gave you a science explanation.Feel proud man =D
What is a fast moving electron?
Fast moving electrons are equivalent to beta radiation.
What is a fast moving electron that is given off as a nuclear radiation?
Beta radioactivity radiation.
What keep the electron in motion around the nucleus to which it is attracted?
the inter nuclear force of attraction between the nucleus and electron keep it moving in a circular manner around the nucleus
What is A fast moving electron that is given off as nuclear radiation?
Beta
What is most of the volume of an atom taken up by?
Moving particles
When an electron moves from a higher energy level to a lower energy level the atom commonly?
The electron moving from a lower to a higher energy level equates to moving from a specific orbit 'r' to a specific orbit 'rr' that is farther from the nucleus.
What is a fast moving electron given off by a nucleus during radioactive decay and has a negative chare?
its called a beta particle, but its an electron
What do you call on the free moving particle around the nucleus of an atom?
The electron moves in a cloud around the nucleus of the particle. Most atoms have several electrons occupying different energy levels and moving in differently shaped orbitals. The electron has a negative charge.
What is a fast-moving electron given off by a nucleus during radioactive decay.?
One part of a beta- particle. The other part is an electron antineutrino
What releases a fast moving electron from a neutron in the nucleus?
In beta decay, a neutron becomes a proton, an electron, and a neutrino (or maybe an anti-neutrino -- we're not sure).
