A hydrogen atom initially in the n=6 quantum state emits a photon having a wavelength of 1.09352E-6 m. What is the quantum number of the final state of the atom?
The nucleus of an atom accounts for... A-most of the size and mass of the atom. B-very little of the size and mass of the atom. C-most of the atom\'s size but very little of its mass. D-most of the atom\'s mass but very little of its size.
If the final temperature was the same for both processes, what is the difference between for the two-step process and for the one-step process in joules
