- where ?∞ = 1.097 × 10^7 m−1is the Rydberg constant and ? is the atomic number (thenumber of protons found in the nucleus). Calculate the ground state energy of a triplyionised beryllium atom, Be3+ (a beryllium atom with three electrons removed).arrow_forward8.10 Apply the variation function = er to the hydrogen atom. Choose the parameter c (which is real) to minimize the variational integral, and calculate the percent error in the ground-state energy. int: -2π [ ø*ødr = [²" ["* "*° φάτ 0 JO = : 2 (277) e-2cr² sino drdodo ofe *Âødt = = e-2cr² dr ħ² · S0₁ | - ²2 μ₁² -2π e-2cr] dr [" sinode [2" de - (c²r²e-2cr -2cre-2cr) - Ze¹2 re-2cr dr Zer21 = 2 (2π) [-1² (2-2) - 202²] 8c3 4c²arrow_forwardUse the Saha equation to determine the fraction of Hydrogen atoms that are ionized Nu/Ntotal at the center of the Sun, where the temperature is 15.7 million K and the electron number density is ne=6.1x1031 /m³. Don't try to compare your result with actual data, as your result will be lower due to not taking the pressure into account. Since most of the neutral H atoms are in the ground state, use Zrdegeneracy3D2 and, since a H ion is just a proton, Zı=1. Also, use XI=13.6 eV.arrow_forward
- The ground-state wave function of a hydrogen atom is: 1 where r is distance from the nucleus and a, is the Bohr radius (53 pm). Following the Born approximation, calculate the probability, i.e., |w?dz, that the electron will be found somewhere within a small sphere of radius, ro, 1.2 pm centred on the nucleus.arrow_forwardThe charge density of the electron cloud of the hydrogen atom is -4-2r/a Pe(r) (1) Ta3 with q > 0 the charge of the proton, and a is the Bohr radius. Compute the polar- izability of the hydrogen atom. Use the approximation of Example 4.1. ASsume the electron cloud is unchanged, but is displaced relative to the proton by -d = -dk with |d < a by an external electric field Eo = Eok. Then, in equilibrium, the force on the proton is F, = 0 = q [E, + E.(d)] (2) where Ee(d) is the electric field created at position d by just the electron charge density Pe(r) (tacking origin of the spherical coordinate system still at the center of the electron charge distribution). Hence use Gauss' Law to find the electric field created by the electron charge density, and then expand your result in powers of d/a 1.arrow_forwardProblem #5: Calculate the equilibrium electron and hole densities for the following samples and determine if they are n-type, p-type or intrinsic: A) Si doped with 7x1017cm-³ Boron atoms. B) Si doped with 2x101$cm-³ phosphorous atoms and with 2x1017cm³ boron atoms. C) Si doped with 2x1018cm3 phosphorous atoms and with 2x1018cm-3 boron atoms.arrow_forward
- (a) Predict the energy in eV of a photon emitted in a transition from the first excited state to the ground state in eV for a system consisting of a nucleus containing Z = 50 protons and just one electron. You need not recapitulate the entire derivation for the Bohr model, but think carefully about the changes you have to make to take into account the factor Z. (b) The negative muon (μ−) behaves like a heavy electron, with the same charge as the electron but with a mass 207 times as large as the electron mass. As a moving μ− comes to rest in matter, it tends to knock electrons out of atoms and settle down onto a nucleus to form a "one-muon" atom. For a system consisting of a nucleus of platinum (Pt195 with 78 protons and 117 neutrons) and just one negative muon, predict the energy in eV of a photon emitted in a transition from the first excited state to the ground state. The high-energy photons emitted by transitions between energy levels in such "muonic atoms" are easily observed in…arrow_forward(1) Calculate (r) and (r²) for the ground state of the hydrogen atom, expressing your answer in term of the Bohr radius. Calculate (x) and (x²) for the ground state of the hydrogen atom. Note that you really do not have to do any more work than you already did in problem #1 if symmetry properties are invoked.arrow_forwardCalculate the speed of the electron in a hydrogen atom in the state n = 5, in m/s. Express your answer as vx 10° m/s and type in just the value of v. Use three decimals in your answer.arrow_forward

(b) What would be the ionization energy of this atom? (c) What would be the wavelength of the transition to the next lowest level?arrow_forwardConsider the Balmer series discussed in the book (and Prof. Scherer's lecture notes), where the frequencies are given by: x (3.29 × 1015 s-1) n = 3,4,5, .. v = Let us focus only on the spectral lines and transitions corresponding to the Balmer series. a) Suppose the Balmer series of hydrogen is studied using a Franck-Hertz experiment. What is the threshold voltage required for n=3? How about n=4? b) The Lyman Series frequencies are given by v = |1- x (3.29 x 1015 s-1). Describe what is different about these two series of emission frequencies of photons from the hydrogen atom? That is, what distinguishes one series from the other? (Hint: it may help to think about the Bohr model interpretation of transitions.)arrow_forwardThis question concerns the addition of 3 angular momenta (as covered in the tutorial).
