rutherfords atomic model

where 'Z' is the nuclear charge, which is equal to atomic number. Although Bohr's model successfully explained the stability and the line spectrum of hydrogen, it had its limitations. They wer..

J.J.Thomson proposed the first simple and most primitive model in 1898, which considered an atom to be a sphere of uniform positive charge into which the negatively charged electrons were embedded. This model was like a plum pudding dotted with raisins and was thus ca..

) This model could not explain the large angle scattering of alpha particles by thin metal foils. Thomson won his Nobel Prize for his discovery of electrons in cathode rays and Rutherford for ascertaining the nature of nucleus and its radi..

Structure of the Atom - Summary Atom is the smallest particle of an element, which maintains its identity throughout chemical and physical changes. Atoms are made up of three fundamental particles: electrons, protons and neutrons. Discharge tube experiments by William ..

Introduction - In the nineteenth century scientists saw enough evidence to prove that each element has its distinctive atom. But all tem atoms contain identical electrons. In spite of the fact that electrons carry negative charge, atoms as whole were found to be neutra..

. But when an electron jumps from a lower energy level to a higher one, some energy is absorbed while some energy is emitted. When an electron jumps from a higher energy level to a lower one, the amount of energy absorbed or emitted is given by the difference of energies associated with the two lev..

fig.12.1 - Space Models of 2-Butenes Note that the atoms are arranged in two different ways in I and II. The two CH 3 groups lie on the same side in I and on the opposite sides in II. When two similar atoms or groups lie on the same side, the isomerism is call..

In order to explain the stability of an atom Neils Bohr in 1913 proposed a new theory to explain the arrangement of electrons in an atom. According to Neils Bohr, the electrons could revolve around the nucleus only in 'certain orbits' (energy levels), each orbit having a differ..

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 balance existing between the nucle..

Question: What is the drawback of Rutherford's nuclear model of the atom? Answer: Drawback of Rutherford's nuclear model: It could not explain the stability of the atom because according to the electromagnetic theory if the char..
