Homework Answers
Option B is correct answer.
Electron orbit around nucleus. If orbit length is integral multiple of wavelengths of electron such orbit or energy level is allowed one. Since integral multiple of wavelengths are discrete , the energy levels of orbits are also discrete

The Bohr Model of the hydrogen atom proposed that there were very specific energy states that the electron could be in. These states were called stationary orbits or stationary states. Higher energy states were further from the nucleus. These orbits were thought to be essentially spherical shells in which the electrons orbited at a fixed radius or distance from the nucleus. The smallest orbit is represented by n=1, the next smallest n=2, and so on, where n is a positive...

2. In the derivation of the energy levels in the hydrogen atom one commonly assumes that the nucleus is a point charge. However, in reality the size of the nucleus is of the order of Im = 10-15m. Since this is very much smaller than the typical distance of the electron from the nucleus, which is of the order of a0-0.5A = 0.5 × 10-10m, the finite size of the nucleus can be taken into account perturbatively. (a) Assume that...

PART A: The electrons in solids can be found ____________in only certain discrete sharp energy states associated with their orbits.in energy states that overlap so that more than one electron is associated with a given energy level.in the same energy states as if the atoms forming the solid were far enough so that their interactions could be neglected.in closely spaced energy levels that form a continuous distribution of energy within a certain range.PART B: When an electron in the valence...

4.8 He-Ne Laser The He-Ne laser system energy levels can be quite complicated, as shown in Figure 4.58. There are a number of lasing emissions in the laser output in the red (632.8 nm), green (543.5 nm), orange (612 nm), yellow (594.1 nm), and in the infrared regions at 1.52 μm and 3.39 μm, which give the He-Ne laser its versatility. The pumping mechanism for all these lasers operations is the same, energy transfer from excited He atoms to Ne...
