atomic model of rutherford

Higher alkanes are similarly formed by the overlap of the orbitals from the neighboring carbon and hydrogen atoms. The carbon atoms in the alkane molecule with more than two carbon atoms do not lie along a straight line but form a zig-zag pattern. Due to sp 3 hybrid ..

Intensive investigation by scientists over the years led to the development of a mental model (the minuscule particles couldn't be actually seen at that time) known as 'dynamic particle model'. All matter is assumed to be made up of particles that are very small, which may be h..

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 - 1 5 m i...

In 1899, the study of radioactivity was taken up by Ernest Rutherford. He placed a little radium at the bottom of a small lead box and subjected the rays that emerged from it to the action of a very strong magnetic field at right angles to their direction. He found that the rays separate..

Solids are substances having definite volume and definite shape. In terms of kinetic molecular model, in solids there is a regular order in the arrangement of the constituting particles (atoms, molecules or ions) i.e. the particles constituting the solids occupy fixed positions ..

It could not explain the line spectrum of multi electron atoms. This model failed to explain the effect of magnetic field on the spectra of atoms (Zeeman effect). The effect of electric field on the spectra could not be explained by Bohr's model (Star..

Suppose an element A disintegrates into another element B. Let number of atoms of A when t = 0 is N 0 . A undergoes continuous disintegration into B and hence the number of atoms of A goes on decreasing. Let the number of atoms of A left undisintegrated in time t b..

Rate of Disintegration - Suppose an element A disintegrates into another element B. Let number of atoms of A when t = 0 is N 0 . A undergoes continuous disintegration into B and hence the number of atoms of A goes on decreasing. Let the number of atoms of A left undisi..

'. So, elements were arranged thereafter not based on the atomic weight but based on the atomic number. With this change the anomalies existed previously vanished automatically. Hence, Moseley re-arranged the periodic table based on atomic number. He expressed his obse..
