removing an electron from a stable nucleus

This is a prominent, spherical or oval structure found at the centre of the cell. It is the controlling centre of all cell activities and has been described as the brain of the cell. It regulates all metabolic and hereditary activities of the cell. The nucleus is composed of the followin..

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..

In this step, energy equal to the ionization energy is absorbe..

The stability of a nucleus is dependent on the type of force which is dominant. The two forces operating inside a nucleus are the electrostatic force of repulsion and the nuclear force of attraction (strong force..

affinity decreases down the group because the number of shells increases i.e., the atomic size increases and the effective nuclear charge decreases. This causes the incoming electron not to experience much attraction of the nucleus thus giving a lower electron affinity..

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 ener..

(i) All these have maximum electron affinities in their respective periods. This is due to the fact that the atoms of these elements have only one electron less than the stable noble gas (ns 2 np 6 ) configurations. Therefore, may have maximum tendency to accept an ad..
