what is nucleus

Nucleus is the most conspicuous and the largest organelle in the cell. Most cells have a single nucleus and hence they are described as uninucleate. Some cells have two nuclei (binucleate) while a few may be even multinucleat..

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..

The Nucleus - Rutherford and his co-workers, performed series of scattering experiments and concluded that the entire mass and the positive charge is concentrated in a very small region at the centre of the atom, known as nucleus. The radius of the nucleus is about 10 ..

The attractive force between the nucleus and the electron increases with the increase in nuclear charge making it more difficult to remove an electron. The ionization energy thus increases with the increase in the nuclear charg..

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 while a proton does (+..

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 nucleus, then the maxim..

Ernest Rutherford, an energetic New Zealander working in England, was studying the properties of particles spontaneously emitted by radioactive substances. Of particular interest was a positively charged, relatively heavy emission named alpha particle. Quantities of such particles are emitted by c..

In 1936, Neils Bohr suggested that the nucleus might be like a droplet of dense liquid, composed of sub droplets of protons and neutrons. A uranium nucleus is spherical in shape. In this spherical nucleus, protons and neutrons are together because of the delicate bala..
