AQA AS-LEVEL PHYSICS 7407/1 PAPER 1 JUNE 2022 QUESTION PAPER. A sample of bromine gas contains a mixture of two isotopes. An experiment is done to find the percentage of each isotope in this sample. 0 2 . 1 In the experiment, the gas is ionised by a beam of electrons. Explain how the beam of electrons causes a particle of the gas to have a charge of +1e. The gas consists of bromine molecules. Each molecule has two bromine atoms. The experiment finds that the bromine molecules contain 158,...
