Give three examples of ions that have an electron configuration of $$n d^{8}(n=3,4,5, \ldots)$$.

Text Transcription:

nd 8 (n = 3, 4, 5, \dots)

Step-by-Step Solution:

Step 1 of 5) Give three examples of ions that have an electron configuration of nd8(n=3,4,5,…). Figure 9.11 shows some examples of polar and nonpolar molecules, all with polar bonds. The molecules in which the central atom is symmetrically surrounded by identical atoms (BF3 and CCl4) are nonpolar. For ABn molecules in which all the B atoms are the same, certain symmetrical shapes—linear 1AB22, trigonal planar 1AB32, tetrahedral and square planar 1AB42, trigonal bipyramidal 1AB52, and octahedral 1AB62—must lead to nonpolar molecules even though the individual bonds might be polar. Polar and nonpolar molecules containing polar bonds. The numbers are electronegativity values. We are given three molecular formulas and asked to predict whether the molecules are polar. Plan A molecule containing only two atoms is polar if the atoms differ in electronegativity. The polarity of a molecule containing three or more atoms depends on both the molecular geometry and the individual bond polarities. Thus, we must draw a Lewis structure for each molecule containing three or more atoms and determine its molecular geometry. We then use electronegativity values to determine the direction of the bond dipoles. Finally, we see whether the bond dipoles cancel to give a nonpolar molecule or reinforce each other to give a polar one.
