52. Using Slaters rules, calculate z* Z+ 4, for Zn. (b) Using Slaters rules, calculate z* Z+ 3 for Zn (c) Calculate (Rmax) for these two orbitals of zinc (d) The covalent radius of zinc is 121 pm; calculate the Alfred Rochov electronegativity OF Zn. How do you think this value compares with the Pauling value of Zn? If you think that it is either substantially (>0.5 units) higher or substantially lower, explain why this is the case 53. In a certain atom, an electron in orbital A experiences an effective nuclear charge Z+. of +4.00, while an electron in orbital B experiences x Z+ of +21.85. Suppose also that the outermost x orbital of this atom is a 6s orbital (n=6, n =4.2), which experiences x Z+ of +2.60, and suppose that the covalent radius of this atom is 170pm, (a) Is orbital A or orbital B more likely a covalent orbital (b) Compute (Rmax) for this atom (c) Compute Xar for this atom 54. In a certain atom, an electron in orbital C experiences an effective nuclear charge Z+ of +14.00, while an electron in orbital D experiences a z* of + 4.85. Suppose also that the outermost s orbital of this atom is a 6s orbital (n+6, n*=4.2), which experiences a Z* of +3.60, and suppose that the covalent radius of this atom is 190 pm (a) Is orbital C or orbital D more likely a valence orbital? (b) Compare (R max) for this atom. (c) Compare Xn for this atom.
