The Bohr model

Students often get confused between Rutherford’s model and Bohr model of an atom. They interpret the postulates of both these models to be the same, which is incorrect. Rutherford’s model differs from Bohr’s model in the following ways:

Marie and Pierre Curie were both winners of the Nobel Prize in physics. This prize is one of the highest any scientist can receive. Their daughter, Irene, also received a Nobel Prize in chemistry. The Curies were a remarkable family. Pierre Curie was already a famous scientist when he met Marie, who had fled from Poland. Together they discovered polonium and radium, two elements that are important in modern industry. Pierre Curie was killed in an accident, but Marie carried on scientific research until she died in 1934. What is the main idea of this paragraph? O 1. the importance of Pierre and Marie Curie's stydies 2. the importance of winning the Nobel Prize 3. the achievements of the outstanding Curie family O 4. Marie Curie's desperate escape from Poland
