Rutherford et bohr

WebThe Bohr model of the atom was proposed by Neil Bohr in 1915. It came into existence with the modification of Rutherford’s model of an atom. Rutherford’s model introduced the nuclear model of an atom, in which he explained that a nucleus (positively charged) is surrounded by negatively charged electrons. Introduction to the Bohr Model WebG1. O modelo de Rutherford, proposto em 1911, contribuiu para o conhecimento do modelo atômico atual. Considerando as propostas de Rutherford, é INCORRETO afirmar que. A) o átomo é constituído de núcleo e eletrosfera. B) a carga negativa do átomo está confinada no núcleo. C) o núcleo contém quase a totalidade da massa do átomo.
