Document Summary

Use the bohr model to calculate the radius and the energy of the b4+ ion in the n = 3 state. The radiation emitted in the transition from n = 3 to n =2 in a neutral hydrogen atom has a wavelength of 656. 1 nm. What would be the wavelength of radiation emitted from a doubly ionized lithium ion (li2+) if a transition occurred from n = Compare these velocities with the speed of light c. as the velocity of an object approaches the speed of light, relativistic effects become important. Name a transition in c5+ that will lead to the absorption of green light. Assume an arbitrary atom x with atomic number (nuclear charge) of z. Ignore the relativistic effects and use bohr model concepts to solve this problem. A fluorescent tube rated at 100 watt emits yellow light of wavelength 590 nm.
