explain the postulates of Rutherford's nuclear model of an atom
Answers
Answer:
Postulates of Rutherford
(1) +ve charge is concentrated in the centre of the atom
called nucleolus.
(2) Electron revolved around the nucleus in circular
paths called orbits.
(3) The nucleolus is much smaller in size than
the atom.
Prawbavle of Rutherford's model
(1) The orbital of the electron is not expected to be
stable
(2) According to Rutherford's model the electron while
moving in their orbit would give up energy
This would make them slow down, gradually
and move towards the nucleus. The electron
will follow a spiral path and then fall
into the nucleus. ultimately the atom would
collapse. But in reality the atom is stable.

Answer:
Postulates of Rutherford atomic model based on observations and conclusions
An atom is composed of positively charged particles. Majority of the mass of an atom was concentrated in a very small region. This region of the atom was called as the nucleus of an atom. It was found out later that the very small and dense nucleus of an atom is composed of neutrons and protons.
Atoms nucleus is surrounded by negatively charged particles called electrons. The electrons revolve around the nucleus in a fixed circular path at very high speed. These fixed circular paths were termed as “orbits.”
An atom has no net charge or they are electrically neutral because electrons are negatively charged and the densely concentrated nucleus is positively charged. A strong electrostatic force of attractions holds together the nucleus and electrons.
The size of the nucleus of an atom is very small in comparison to the total size of an atom.
