Answer to relevant QuestionsAccording to the Bohr theory of the hydrogen atom, the speed of the electron in the first Bohr orbit is 2.19 x 106 m/s. (a) What is the wavelength of the matter wave associated with the electron? (b) How does this ...(a) How many possible sets of quantum numbers are there for the n = 1 and n = 2 shells? (b) Write the explicit values of all the quantum numbers (n, ℓ, mℓ, ms) for these levels. Identify the atoms of each of the following ground state electron configurations: (a) 1s2 2s2; (b) 1s2 2s2 2p3; (c) 1s2 2s2 2p6; (d) 1s2 2s2 2p6 3s2 3p4. What is the minimum uncertainty in the speed of an electron that is known to be somewhere between 0.050 nm and 0.10 nm from a proton? An electron traveling at 3.00 x 104 m/s is further accelerated by a potential difference so as to reduce its de Broglie wavelength to one-third of its original value. How much voltage is required to accomplish this?
