("electron in a finite square potential well") electron can travel within a thin conducting tube, consisting of three electrically disconnected segments. the first and the third segment are at the potential и--9 v, whereas the second one is at ½ 0 v, both measured with respect to the ground. the electron has kinetic energy ke-2 ev in the region with potential v. (a) what is the kinetic energy of the electron in the middle region? (b) sketch a graph of the potential energy of the electron as a function of the distance from the center of the tube. assume each piece has a length l (c) usually, the electron will simply pass through. however, while in the central region, if the electron emits a photon, it can lose enough kinetic energy to become trapped between -l/2 and +l/2. the energy levels of the electron within the trap are: e ev, e2-2 ev, and es-4 ev, and the non-quantized region begins at e4-9 ev. what is the smallest energy the emitted photon can have?

The orbital diagram represents the filling of electrons in the sub levels of an orbit. The filling of the orbitals in sub- levels follow some basic rules and principles.

The orbital diagram of an orbit containing 16 electrons will be as follows:

    1s²2s²2p⁶3s²3p⁴

The maximum number of electrons in each sublevel of the orbitals are:                  2 electrons for s-sublevel with one orbital                  6 electrons for p-sublevel with three orbital                  10 electrons for d-sublevel with five orbital                  14 electrons for f-sublevel with seven orbital
