Here is a test to see what  you know about Dalton's atomic theory with this:   Interactive video 💥 Here are some problems to practice: 1.    The hydrogen atom absorbs energy so that the electrons are excited to the energy level n = 7. The electrons then undergo these transitions: 1) n = 7 to n = 1; 2) n = 7 to n = 2; 3) n = 2 to n = 1. Which of these transitions will produce a photon with: a. The lowest energy b. The highest frequency c. The shortest wavelength. 2.  Chlorine found in nature is 75.78% of 35Cl (atomic mass of 34,969 amu ) and 24.22% of 37Cl (atomic mass of 36,966 amu). Calculate the average atomic mass of chlorine 3.  Calculate the frequency of radiation of the following wavelength: - 8973 Å
