Question

write the reàsons of Rutherford's observation​

Answer 1

Explanation:

Based on the above observations and conclusions, Rutherford proposed the atomic structure of elements. According to the Rutherford atomic model: The positively charged particles and most of the mass of an atom was concentrated in an extremely small volume. He called this region of the atom as a nucleus.

Answer 2

Answer and Explanation:

$\diamond$ Ernest Rutherford was a New-zealand born British physicist

$\diamond$ He conducted an experiment in 1908 called as the Rutherford's alpha scattering experiment or Rutherford's gold foil experiment

$\diamond$ In this experiment, an alpha-particle emitter emitted out alpha-particles into a thin gold foil of thickness 1000 atoms

$\diamond$ The thin foil was surrounded by a fluorescent screen

$\diamond$ The fluorescent screen on hit by an alpha-particle produced a fluorescent light

$\diamond$ Rutherford's observations after his experiment were :

1. Most of the alpha-particles went through the atoms
2. Some of the alpha-particles were deflected in various angles
3. Very few alpha-particles rebounded back

$\diamond$ Rutherford's conclusion from his experiment were :

1. Most of the space inside the atom is empty because most of the alpha-particles passed through the gold foil without getting deflected
2. Very few particles were deflected from their path, indicating that the positive charge of the atom occupies very little space

$\diamond$ His observations are the reasons why he concluded with these conclusions

$\diamond$ The figure given below shows the atoms and alpha-particles
