Open Answer »Rutherford’s atomic model was a reasonably good model of structure of atom based on at the famous particle scattering experiment. However, it was subsequently modified by Neils Bohr and later on, by others. The resulting improvements in the understanding of atomic structure have greatly contributed to further scientific advancement. There are many other similar examples in scientific field when original contributors happily accept modifications in their ideas. Answer the following questions based on the above information: (𝒊) Name the scientific values associated with above anecdotes. (𝒊𝒊) Give any example from your life experiences so far which reflects display of such a value by you as an individual. (𝒊𝒊𝒊) In what way such a personal attribute is likely to help you?
