Particle with two protons and two neutrons ejected during decay?

An alpha particle. It is also a helium nucleus and has a charge of +2e. The ejection of an alpha particle occurs whenever the electromagnetic force overcomes the strong force in a nucleus and needs to rid itself of excess charge. The reason that a single proton is not simply ejected has to do with the stability of the alpha particle itself which is generated by the strong force. If there were more protons in an alpha particle, it would not hold together properly. It cannot have more neutrons because it simply wouldn't be ejected because of strong force.

What element will result if two protons and two neutrons are ejected from a uranium nucleus?
If two protons and two neutrons are removed from a uranium nucleus, the new element is thorium. The isotope cannot be determined because the identity of the uranium isotope was not given.
Can particles leave the atom?
Yes. This process is called radioactive decay. The primary particles emitted are alpha particles, which are helium-4 nuclei, and beta particles, which are electrons.
What is a beta partical?
A Beta Particle is a high energy electron that comes from the nucleus, not from the electron cloud. However, the nucleus contains only protons and neutrons. During this kind of transmutation, a neutron becomes unstable and splits into an electron and a proton. The electron, or beta particle, is released with a large amount of energy. The proton however, remains in the nucleus.P.S. I got this information out of my Science text book. (:
What particle is emitted in beta radiation?
In unstable neuclei where there are 'too many' neutrons, a neutron will convert to a proton and an electron - that electron is ejected from the nucleus and is called a beta particle. It is important that we call this electron a beta particle because it is derived by radioactive disintegration in the nucleus and not an 'orbital' electron.
How many protons does a nitrogen ion contain?
Ionization involves addition or removal of an electron from an atom. No change to the nucleus (where the protons and neutrons live) occurs during ionization. Thus, the nitrogen ion has the same number of protons before and after ionization, and that would be seven. A chemist
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?
an alpha particle
What is the partical with two protons and two neutrons ejected during decay?
Alpha particle.
What is a subatomic particle with two neutrons that is emitted during some types of radioactive decay called?
This would be the alpha particle. An alpha particle has two neutrons and two protons, and it's actually a helium-4 nucleus. That's why we write this particle like this: 42He or He+2 Use the links below for more information.
What element will result if two protons and two neutrons are ejected from a uranium nucleus?
If two protons and two neutrons are removed from a uranium nucleus, the new element is thorium. The isotope cannot be determined because the identity of the uranium isotope was not given.
Protons and neutrons are found in this part of an atom?
Protons and neutrons are found in the nucleus of an atom. These subatomic particles "bond" together during fusion to create the nucleus.
What type of particles are released as part of alpha decay?
It is the alpha particle, which is actually a helium-4 nucleus, that is emitted during alpha decay. The helium-4 nucleus, you'll recall, consists of two protons and two neutrons.See the links below for more information.
What happens to an isotope during radioactive?
That depends on the specific radioisotope. For instance, uranium 238 emits an alpha particle during radioactive decay, reducing the number of protons and neutrons in the nucleus by 2 each and producing thorium 234. On the other hand, carbon 14 emits a beta particle (an electron) during radioactive decay, decreasing the number of neutrons and increasing the number of protons by 1 each and producing nitrogen 14. There are quite a few other examples with different changes depending on the type of radioactive decay.

Which type of nuclear substance is a helium nucleus?
The alpha particle has a composition identical to a helium nucleus, specifically, the nucleus of helium-4. The alpha particle, however, is a product of radioactive decay, and is usually moving pretty fast. When we speak of helium nuclei, we are usually speaking of things that are much less energetic.
Was it 1 second after the big bang that protons and neutrons formed?
Yes, it was during the Hadron Epoch.
How is it possible that negatively charged beta particles are emitted from a positively charged nucleus during nuclear decay?
An electron (negative particle) and an electron neutrino (neutral particle) are released when a neutron (neutral particle) changes into a proton(positive particle) therefore in order for neutral charge to create a positive particle it also has to create a negative particle to balance it out.As a significant amount of binding energy is released, the electron is ejected at high velocity as beta radiation while the much more massive nucleus containing the newly created proton recoils with very low velocity. The neutrino having almost no mass is ejected at almost the speed of light, but is nearly impossible to detect except by implication from the "missing momentum".Basically beta particles are ejected from the nucleus by conservation of momentum before and after the decay event.
