electron capture nucleus

In some nuclides, the nucleus may capture an electron from the K - shell. The vacancy created is filled by electrons from higher levels giving rise to characteristic X - rays. This process is known as K - electron capture or simply K - ..

On the basis of Heisenberg's uncertainty principle, it can be shown as to why electron cannot exist within the atomic nucleus. The radius of the atomic nucleus is of the order of 10 - 1 5 m. Now, if the electron were to exist within the nucleush..

Atomic Nucleus - It is the central core of the atom where the entire +ve charge and mass is concentrated. It is a tiny sphere of diameter ranging from 10 - 1 5 m to 10 - 1 4 m. A nucleus is made up of particles called neutrons and protons. A neutron does not carry any charge whi..

When the nuclear charge is high there is greater attraction for the incoming electron. Therefore electron affinity increases as the nuclear charge increases. With the increase in the size of the atom the electron affinity decreases because the distance between the..

Cyclic Electron Transport System - Cylic reaction transport occurs only occasionally when synthesis of carbohydrate is curtailed due to limited supply of CO 2 and NADPH 2 starts accumulating. At this time, there would be no need for additional NADPH 2 . Moreover, the cyclic electronh..

From chlorine to iodine, which ionize by accepting one electron there is a decrease in the electron affinity or the energy released. The lower electron affinity of fluorine when compared to chlorine is not fully understood. ..

In order to represent the structures of the combining elements in the most simplest way in terms of the valence electrons on paper, Lewis proposed the following notation: The symbols of the element is written first. This represents the nucleus of the element with all the inne..

Electrons revolve around the nucleus in different energy levels or shells and each shell is associated with definite energy. The energy of the K shell is the least while those of L, M, N and O shells increases progressively. We also know that any system that has least energy is..
