- Identify the shell, subshell, and number of electrons for the following: (a)2p3 . (b) 4d9 . (c) 3s1 . (d) 5g16 .arrow_forward11. (a) What part of the original Bohr model still seems to be well supported by experimental evidence? (b) Identify one weakness in Bohr's atomic theory.arrow_forward(A) A photon has a wavelength of 599 nm. Calculate the energy of the photon in joules. Enter your answer in scientific notation. (b) what is the wave length (in nm) of radiation that has an energy content of 9.53 x 103 kJ/mol? (B part 2) in which region of the electromagnetic spectrum is this radiation found? (c) what are the possible values for ml when the principal quantum number (n) is 2 and the angular momentum quantum number is 0?arrow_forward

(a) What is the smallest orbital angular momentum it could have? (b) What is the largest orbital angular momentum it could have? Express your answers in terms of h and in SI units. (c) What is the largest orbital angular momentum this electron could have in any chosen direction? Express your answers in terms of h and in SI units. (d) What is the largest spin angular momentum this electron could have in any chosen direction? Express your answers in terms of h and in SI units. (e) For the electron in part (c), what is the ratio of its spin angular momentum in the z-direction to its orbital angular momentum in the z-direction?arrow_forwardParticles called muons exist in cosmic rays and can be created in particle accelerators. Muons are very similar to electrons, having the same charge and spin, but they have a mass 207 times greater. When muons arecaptured by an atom, they orbit just like an electron but with a smaller radius, since the mass in aB =0.529x 10-10 m is 207 me .(a) Calculate the radius of the n=1 orbit for a muon in a uranium ion( Z=92).(b) Compare this with the 7.5-fm radius of a uranium nucleus. Note that since the muon orbits inside the electron, it falls into a hydrogen-like orbit. Since your answer is less than the radius of the nucleus, you can seethat the photons emitted as the muon falls into its lowest orbit can give information about the nucleus.arrow_forward
