Chapter 2: Problem 65

Predict whether each of the following compounds is molecular or ionic: (a) \(\mathrm{B}_{2} \mathrm{H}_{6},(\mathbf{b}) \mathrm{CH}_{3} \mathrm{OH},(\mathbf{c}) \mathrm{LiNO}_{3},(\mathbf{d}) \mathrm{Sc}_{2} \mathrm{O}_{3}\) (e) \(\mathrm{CsBr},(\mathbf{f}) \mathrm{NOCl},(\mathbf{g}) \mathrm{NF}_{3},(\mathbf{h}) \mathrm{Ag}_{2} \mathrm{SO}_{4}\)

Short Answer

Expert verified
(a) B2H6: molecular, (b) CH3OH: molecular, (c) LiNO3: ionic, (d) Sc2O3: ionic, (e) CsBr: ionic, (f) NOCl: molecular, (g) NF3: molecular, (h) Ag2SO4: ionic.

Step by step solution

01

(a) B2H6 (Boron Hydrogen)

As Boron (B) and Hydrogen (H) are both non-metal elements, the compound B2H6 is molecular.
02

(b) CH3OH (Methanol)

Since Carbon (C), Hydrogen (H), and Oxygen (O) are all non-metal elements, the compound CH3OH is molecular.
03

(c) LiNO3 (Lithium Nitrate)

Because Lithium (Li) is a metal element, and Nitrogen (N) and Oxygen (O) are non-metal elements, the compound LiNO3 is ionic.
04

(d) Sc2O3 (Scandium Oxide)

As Scandium (Sc) is a metal element and Oxygen (O) is a non-metal element, the compound Sc2O3 is ionic.
05

(e) CsBr (Cesium Bromide)

Since Cesium (Cs) is a metal element and Bromine (Br) is a non-metal element, the compound CsBr is ionic.
06

(f) NOCl (Nitrosyl Chloride)

Given that Nitrogen (N), Oxygen (O), and Chlorine (Cl) are all non-metal elements, the compound NOCl is molecular.
07

(g) NF3 (Nitrogen Trifluoride)

As Nitrogen (N) and Fluorine (F) are both non-metal elements, the compound NF3 is molecular.
08

(h) Ag2SO4 (Silver Sulfate)

Because Silver (Ag) is a metal element, and Sulfur (S) and Oxygen (O) are non-metal elements, the compound Ag2SO4 is ionic.

What fraction of the \(\alpha\) particles in Rutherford's gold foil experiment are scattered at large angles? Assume the gold foil is two layers thick, as shown in Figure \(2.9,\) and that the approximate diameters of a gold atom and its nucleus are 2.7 A and \(1.0 \times 10^{-4} \hat{\mathrm{A}}\) , respectively. Hint: Calculate the cross sectional area occupied by the nucleus as a fraction of that occupied by the atom. Assume that the gold nuclei in each layer are offset from each other.
