14. The picture below shows a cross-section of the electron density of an orbital (dark areas represent electron density). a) Which orbital is represented? Identify the features that allow you to identify the orbital unambiguously. (2) b) In the coordinate system to the right, qualitatively draw the corresponding radial wave function. (3) intensity of wave function distance r from nucleus

Match the d orbital with its shape. (1) (2) (3) Orbital Selection p d,2-y2 P Type here to search # メ a W %23 6 80 GH

The number of angular and radial nodes in 3p orbital respectively are (a) 3,1 (b) 1,1 (c) 2,1 (d) 2,3

PLEASE SOLVE A), B) AND C) PLEASE IS VERY IMPORTANT A, B AND C TOPIC: ATOMIC PHYSICS Using Slater's rules to estimate the effective nuclear charge Z * by shielding in atoms of many electrons, obtain Z * for the following orbitals and atoms (list your results in a table and refer to the electron configurations of the base states in a Periodic Table ): (a) of the electronic configuration of the atoms in the ground state to promote a valence electron to a 3d orbital traveling atoms from H (hydrogen, Z = 1) to K (potassium, Z = 19); (b) the same as in (a) but promoting the valence electron to a 4s orbital; (c) Comparing (a) and (b) what interpretation can be given to the results in terms of the dependence of the energies of the 3d and 4s orbitals from Z = 1 to 19? What consequence does the above have regarding the filling of 3d and 4s orbitals from Z = 1 to 19?
