AQA-7405-1-CHEMISTRY QUESTION PAPER 1-A-LEVEL-INORGANIC AND PHYSICAL CHEMISTRY-10Jun24. 0 1 This question is about atomic structure. 0 1 . 1 In 1897 JJ Thomson discovered the electron. He suggested that atoms were positively charged spheres with electrons embedded within them. Figure 1 represents an atom using Thomson’s model. Figure 1 Suggest the identity of this atom. Give two differences between the modern model of an atom and the Thomson model of an atom. [3 marks] Identity Di...
