Dalton atomic model tadiya mndenw??

[@ethioeducationtub6677]

Thank you so much for your comment. The correct answer choice D , because Dalton’s work was
mainly about the chemistry of atoms - how they combine to form new compounds -
rather than about the internal structure of atoms. However, Dalton never denied the
possibility of atoms having a structure. Modern theories about the physical structure of
atoms did not begin until J.J. Thomson discovered the electron in 1897 Refer grade 11 old text book .page 48 in PDF
