explain the observation and their explanation in Rutherford's model of an atom. right postulates of structure of atom given by Rutherford
Answers
Answer:
Observations of Rutherford’s Alpha Scattering Experiment
The observations made by Rutherford led him to conclude that:
A major fraction of the α-particles bombarded towards the gold sheet passed through it without any deflection, and hence most of the space in an atom is empty.
Some of the α-particles were deflected by the gold sheet by very small angles, and hence the positive charge in an atom is not uniformly distributed. The positive charge in an atom is concentrated in a very small volume.
Very few of the α-particles were deflected back, that is only a few α-particles had nearly 180° angle of deflection. So the volume occupied by the positively charged particles in an atom is very small as compared to the total volume of an atom
Rutherford Atomic Model
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.
Rutherford model proposed that the negatively charged electrons surround the nucleus of an atom. He also claimed that the electrons surrounding the nucleus revolve around it with very high speed in circular paths. He named these circular paths as orbits.
Electrons being negatively charged and nucleus being a densely concentrated mass of positively charged particles are held together by a strong electrostatic force of attraction
Explanation:
Postulates of Rutherford atomic model based on observations and conclusions.
An atom is composed of positively charged particles. ... An atom has no net charge or they are electrically neutral because electrons are negatively charged and the densely concentrated nucleus is positively charged.
Answer:
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. Rutherford model proposed that the negatively charged electrons surround the nucleus of an atom.
