Chapter 10: Problem 142

Without referring to tables or figures in the text other than the periodic table, indicate which of the following atoms, \(\mathrm{Bi}, \mathrm{S}, \mathrm{Ba}, \mathrm{As},\) or \(\mathrm{Mg},\) has the intermediate value when they are arranged in order of increasing electronegativity.

Short Answer

Expert verified
The atom with an intermediate electronegativity value when Bi, S, Ba, As, and Mg are arranged in order of increasing electronegativity is As.

Step by step solution

01

Identify the Positions on the Periodic Table

The first step is to identify where the given atoms, Bi, S, Ba, As, and Mg, are located on the periodic table:
02

Identify the Electronegativity Trends

The next step is to apply the understanding of the trends in electronegativity across the periodic table. Electronegativity tends to increase as moving from left to right across a period and decrease as moving down a group. Remember that the farthest to the left and down, the atom with the lowest electronegativity, and the farthest to the right and up, the atom with the highest electronegativity.
03

Arrange in Order of Electronegativity

Now arrange all the atoms in order of increasing electronegativity based on their positions in the periodic table. From left to right, and bottom to top:
04

Identify Atom with Intermediate Electronegativity

Finally, the atom having an intermediate value of electronegativity is the one in the middle of this arranged list.

Write acceptable Lewis structures for the following molecules: (a) \(\mathrm{H}_{2} \mathrm{NNH}_{2}\); (b) HOClO; (c) (HO) \(_{2}\) SO; (d) HOOH (e) SO \(_{4}^{2-}\).

Write a plausible Lewis structure for \(\mathrm{NO}_{2}\), and indicate whether the molecule is diamagnetic or paramagnetic. Two \(\mathrm{NO}_{2}\) molecules can join together (dimerize) to form \(\mathrm{N}_{2} \mathrm{O}_{4}\). Write a plausible Lewis structure for \(\mathrm{N}_{2} \mathrm{O}_{4},\) and comment on the magnetic properties of the molecule.

Draw Lewis structures for two different molecules with the formula \(\mathrm{C}_{3} \mathrm{H}_{4}\). Is either of these molecules linear? Explain.

The following statements are not made as carefully as they might be. Criticize each one. (a) Lewis structures with formal charges are incorrect. (b) Triatomic molecules have a planar shape. (c) Molecules in which there is an electronegativity difference between the bonded atoms are polar.

Draw three resonance structures for the sulfine molecule, \(\mathrm{H}_{2} \mathrm{CSO}\). Do not consider ring structures.
