Write any THREE features of rruthan forkes atomic model ??
Answers
Three features of Rutherford's Atomic Model are
i) The atom contains a central part called nucleus which is surrounded by electrons.
(ii) The nucleus of an atom is positively charged.
(iii) The size of the nucleus is very small as compared to the atomic size.
(iv) The mass of an atom is mainly concentrated within its nucleus.
(v) Atom as a whole is electrically neutral, i.e., number of protons inside the nucleus of an atom and the number of electrons surrounding it are equal.
(vi) Nucleus is dense and hard and most of the atom is hollow.
(vii) To explain that the electrons do not fall into the nucleus because of attraction, Rutherford said that electrons were not stationary but were revolving around the nucleus in certain circular orbits. The force of attraction is balanced by the centrifugal force which comes into play due to revolution.
