Rutherford gold foil scattering experiment full explanation in pints
Answers
1. Am atom consists of a positively charged,dense and very small nucleus containing all the protons and neutrons.
2. The nucleus is surrounded by negatively charged electrons.
3. The electrons are revolving round the nucleus in circular pathan very high speeds.
4. The electrostatic attraction between the positively charged nucleus and negatively charged electrons holds the atom together.
5.An atom is electrically neutral.This is because the no. of protons ans electrons in an atom is equal.
6.Most of the atom is empty space.
When fast moving alpha particles are allowed to strike a very thin gold foil in vacuum,it is found that:
1.Most of the Alpha particles pass straight through the gold foil without any deflection from their original path .
2.A few alpha particles are deflected through small angles and a few are deflected through large angles .
3.A very few alpha particles completely rebound on hitting the gold foil and turn back on the path.
Those alpha particles which were hitted by nucleus rebound or deflected.
By these we can conclude that Rutherford's gold foil experiment discovered nucleus.
