alpha decay protons

Alpha decay is the phenomenon of emission of an a - particle from radioactive nucleus...

Radioactive nuclei being unstable, emit radiations to achieve states of greater stabilit..

Radioactive Decay or Disintegration - A radioactive nucleus or element emits an alpha or a beta particle and gets converted into a new nucleus or element. The process of destruction of the original nucleus during the formation of new nucleus due to radioactivity is called Radioa..

The stability linked to the n - p ratio is explained by strong n - p as well as p - p attractive forces operative at the level of nuclear distances. For heavier nuclides, p - p repulsions start to offset the attractive forces and an excess of neutrons over protons is required for stabilit..

When the value of Z becomes greater than 82, some nuclides attain greater stability (i.e., decay by a - emission) which reduces the initial N/Z value to (N - 2) / (Z - 2). Reduction of Z leads to the reduction of p - p repulsions. Example of a - emissio..

b - particle, and reverts to nitrogen In nature, radiocarbon is formed when high energy atomic particles called cosmic rays break down the atoms in the atmosphere into electrons, protons, neutrons and other particles. Some of the neutrons strike the nuclei of nitrogen atoms in the ..

They are deflected by electric and magnetic fields. The deflection is less compared to that of b particles, because a particles are heavy. They affect a photographic plate and cause fluorescence on striking a fluorescent material. They ionise the gas through which they pass. The mass..

Alpha rays consist of stream of positively charged particles carrying charge of +2 units and a mass of four units on the atomic weight scale (i.e., 4 amu). They consist of 2 protons and 2 neutrons. In other words, these particles are helium nuclei and therefore indicated as 2..
