Write the postulates and drawback of rutherford atomic
Answers
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.
The answer of ur question is
♢ Atom is spherical and almost hollow inside .
♢ Protons reside inside the centre of the atom called as nucleus
♢ The whole mass of the atom is concentrated at its nucleus
♢ Electrons revolve around the nucleus along the circular paths called orbits
♢ Number of electrons =Number of proton
So, the atom is neutral
