Unreasonable result. Which of die following spectroscopic notations are not allowed? (a) 5s1 (b) 1d1(c) 4s3(d) 3??(e) 5g15 . State which rule is violated for each notation that is not allowed.
A physicist is watching a 15-kg orangutan at a zoo swing lazily in a tire at the end of a rope. He (the physicist) notices that each oscillation takes 3.00 s and hypothesizes that the energy is quantized. (a) What is the difference in energy in joules between allowed oscillator states? (b) What is the value of n for a state where the energy is 5.00 J? (c) Can the quantization be observed?
Atomic and molecular spectra are discrete. What does discrete mean, and how are discrete spectra related to the quantization of energy and electron orbits in atoms and molecules?
The rate at which solar wind particles enter the atmosphere is higher during the day than at night, yet the intensity of the auroral emissions remains high well after the Sun has set. Can you suggest a means by which the atmospheric molecules might be able to radiate long after the period of collisions with charged particles has ended? (Hint: How long does it take a typical atom to radiate from a normal allowed energy state? How could this time be lengthened?)
7.123 One way to estimate the effective charge (Zeff) ofa many-electron atom is to use the equation IE1 =(1312 kJ/mol) (Z2eff/n2), where IE1 is the first ionizationenergy and n is the principal quantum number of theshell in which the electron resides. Use this equation tocalculate the effective nuclear charges of Li, Na, and K.Also calculate Zeff/n for each metal. Comment on yourresults.

Disscuse particle problem; In the octatetraene (C8H10) molecule, one π electron is from the top filled level. What should be the length of the electromagnetic wave required to excite to the lowest null level? The length of the molecule can be taken as 9.5 Å. The experimental value you found is λ4.5 =3020 Å. Discuss whether the particle-in-a-box problem is a good approximation by comparing it to the problem below.
The alkali metals have the lowest ionization energies (Figure ), yet they have the largest atomic radii (Figure). Is this consistent? Explain.

Photoconductivity and speed Consider two p-type Si samples both doped with 1015 B atoms cm−3. Both have identical dimensions of length L (1 mm), width W (1 mm), and depth (thickness) D (0.1 mm). One sample, labeled A, has an electron lifetime of 1 μs whereas the other, labeled B, has an electron lifetime of 5 μs. a. At time t = 0, a laser light of wavelength 750 nm is switched on to illuminate the surface (L × W) of both the samples. The incident laser light intensity on both samples is 10 mW cm−2. At time t = 50 μs, the laser is switched off. Sketch the time evolution of the minority carrier concentration for both samples on the same axes. b. What is the photocurrent (current due to illumination alone) if each sample is connected to a 1 V battery?
