what is the charge of the nucleus of an atom

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 1..

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..

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 charge..

The existence of negative and positive charges on these materials can be explained on the basis of the structure of the atom. Almost all the mass of an atom resides in a central nucleus which contains a number of tightly packed protons and neutrons. As the pr..

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 em..

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 multinucleate. A nucleus generally o..

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 distance from the nucleus to the outermost shell depends on the electrostatic attraction (nuclear charge) that the nucleus exerts on the electrons of the outer shell. More the nuclear charge closer are the shell and electrons, hence smaller is the at..
