Radioactivity is a nuclear phenomenon in which an unstable nucleus decays into a more stable nucleus. The given reaction is an example of beta plus decay in which a positron and a neutrino are emitted from the nucleus.Answer and Explanation: The nuclear reaction involving the conversion of ...
When an antiparticle and a particle are within their ideals quantum states, they can annihilate each other and form other particles. The existence of antiparticles is described within the quantum field theory. Carl Anderson played a significant role is the discovery of antiparticle while he was ...
What are elementary particles in nuclear physics? What are the three subatomic particles? What force does the Higgs boson carry? How big is a subatomic particle? What is positron emission? What particles are outside the nucleus of the atom?Explore...
We suggest that intra-nuclear cascading produces very high multiplicities in processes where a very fast cosmic ray proton strikes a nuclear target. Only particles produced in the central region of the production process are expected to participate in the cascade....
"still more recently, science claimed that all of the different particles are themselves made out of different combinations of just a few particles called quarks and that those are the ultimately existing things. but they have not yet progressed far enough. the simple fact of the matter is ...
Most atoms have three different subatomic particles inside them: protons, neutrons, and electrons. The protons and neutrons are packed together into the center of the atom (which is called the nucleus) and the electrons, which are very much smaller, whizz around the outside. When people draw ...
thus apparently jumping the air gap and escaping its prison. A similar thing happens at the sub-atomic scale, when alpha particles try to escape from unstable nuclei during radioactive decay. The particles are effectively held in the nucleus by the nuclear forces and, in principle, should not...
Protons are the subatomic particles of an atom that are positively charged.Answer and Explanation: The center of an atom is called nucleus. Nucleus was discovered by Ernest Rutherford and his students through an experiment termed the gold foil......
