AQA Chemistry As Level Paper 1

Section A Answer all questions in this section. 0 1 This question is about atomic structure. In the nineteenth century JJ Thomson discovered the electron. He suggested that negative electrons were found throughout an atom like ‘plums in a pudding of positive charge’. Figure 1 shows an atom of element R using the ‘plum pudding’ model. An atom of R contains seven electrons. Figure 1 0 1 . 1 State two differences between the ‘pl...
