Briefly describe Rutherford’s model of an atom
Answers
Rutherford's model of an atom
1.An atom consist of positively charge nucleus around which negatively charged electrons move
2.Electron and proton remain together by electrostatic force of attraction
3.An atom is neutral
4.In an atom volume of nucleus is very small as compare to an atom
5.Entire mass of an atom is concentrated in nucleus
6.Most of the spaces in an atom is empty
Demerit of Rutherford's model
According to him negatively charge electron revolve around positively charged nucleus but due to electrostatic force of attraction elactron fall in side the nucleus and the atom vanished
Answer:
Rutherford Atomic Model – The plum pudding model is given by J. J. Thomson failed to explain certain experimental results associated with the atomic structure of elements. Ernest Rutherford, a British scientist conducted an experiment and based on the observations of this experiment, he proposed the atomic structure of elements and gave Rutherford Atomic Model.
Rutherford’s Alpha Scattering Experiment
Rutherford’s conducted an experiment by bombarding a thin sheet of gold with α-particles and then studied the trajectory of these particles after their interaction with the gold foil.
Rutherford Atomic Model
Rutherford, in his experiment, directed high energy streams of α-particles from a radioactive source at a thin sheet (100 nm thickness) of gold. In order to study the deflection caused to the α-particles, he placed a fluorescent zinc sulphide screen around the thin gold foil. Rutherford made certain observations that contradicted Thomson’s atomic model.
