1: Part A: Two electrons occupy the 2s shell in a Be atom (Z = 4). What are the possible quantum numbers J for the total angular momentum of this two-electron system, neglecting any contributions from the nucleus or 1s level? Part B: Calculate the energy required to cause an electron from the 2s shell to jump to each of the 2p, 3s, 3p, and 3d states. E1 for Be is 9.3 eV. En = (-Z2E1)/n2. One of the listed...

Consider an electron in a 2s orbital of hydrogen (Z=1). Calculate the probability that the electron will be found anywhere in a shell formed by a region between a sphere of radius r and radius 1.0pm greater than the r value. Do this calculation in Excel for r from 1 to 600 pm in increments of 1pm. (You will be calculating the probability for successive shells at greater and greater distances from the nucleus.) Plot the resulting curve with probability...

Expectation values. Calculate the expectation value of the distance of an electron in a hydrogen atom from its nucleus when the electron is in its ground state. Let the wave function of the electron be: 1/2 rao) exp(-r/a.) where: ao is a constant 0.529 A, and r is the separation of the point of observation from the point nucleus. Hint: to solve this problem, remember that the "expectation integral" is done over the volume of all space! So you must...

3.27 Average distance from the nucleus and atomic radius The maximum in the radial probability distribution of an electron in a hydrogen-like atom is given by Equation 3.58, that is, rmax - (n'ao)/Z, for l - n- 1. The average distance F of an electron from the nucleus can be calculated by using the definition of an average and the probability distribution function Pn/(r), that is, Z. elective 2 2n2 in which the right-hand side represents the result of the...
