Chapter 2: Problem 97

Using a suitable reference such as the CRC Handbook of Chemistry and Physics or http://www.webelements.com, look up the following information for nickel: (a) the number of known isotopes, \((\mathbf{b})\) the atomic masses (in \(\mathrm{u}),(\mathbf{c})\) the natural abundances of the five most abundant isotopes.

Short Answer

Expert verified
There are 31 known isotopes of Nickel. The atomic masses (in u) of the five most abundant isotopes are: Nickel-58: 57.9353479 u, Nickel-60: 59.930791 u, Nickel-61: 60.931060 u, Nickel-62: 61.928348 u, and Nickel-64: 63.927971 u. The natural abundances of these isotopes are: Nickel-58: 68.077%, Nickel-60: 26.223%, Nickel-61: 1.140%, Nickel-62: 3.635%, and Nickel-64: 0.925%.

Step by step solution

01

Research about Nickel isotopes

Go to the website http://www.webelements.com, and find the information about Nickel (Ni) isotopes.
02

Number of known isotopes

After visiting the webpage, we find that there are 31 known isotopes of Nickel.
03

Atomic masses of the five most abundant isotopes

From the given source, we acquire the atomic masses (in u) of the five most abundant isotopes of Nickel as follows: 1. Nickel-58: 57.9353479 u 2. Nickel-60: 59.930791 u 3. Nickel-61: 60.931060 u 4. Nickel-62: 61.928348 u 5. Nickel-64: 63.927971 u
04

Natural abundances of the five most abundant isotopes

Using the provided source, we get the natural abundances of the five most abundant isotopes of Nickel: 1. Nickel-58: 68.077% 2. Nickel-60: 26.223% 3. Nickel-61: 1.140% 4. Nickel-62: 3.635% 5. Nickel-64: 0.925% Now, all the information requested in the exercise has been collected. In summary: (a) There are 31 known isotopes of Nickel. (b) The atomic masses (in u) of the five most abundant isotopes are: - Nickel-58: 57.9353479 u - Nickel-60: 59.930791 u - Nickel-61: 60.931060 u - Nickel-62: 61.928348 u - Nickel-64: 63.927971 u (c) The natural abundances of the five most abundant isotopes are: - Nickel-58: 68.077% - Nickel-60: 26.223% - Nickel-61: 1.140% - Nickel-62: 3.635% - Nickel-64: 0.925%

Write the chemical formulas for the following compounds: (a) aluminum hydroxide, \((\mathbf{b})\) potassium sulfate, \((\mathbf{c})\) copper(I) oxide, \((\mathbf{d})\) zinc nitrate, \((\mathbf{e})\) mercury(II) bromide, (f) iron(III) carbonate, \((\mathbf{g})\) sodium hypobromite.

Mass spectrometry is more often applied to molecules than to atoms. We will see in Chapter 3 that the molecular weight of a molecule is the sum of the atomic weights of the atoms in the molecule. The mass spectrum of \(\mathrm{H}_{2}\) is taken under conditions that prevent decomposition into \(\mathrm{H}\) atoms. The two naturally occurring isotopes of hydrogen are ${ }^{1} \mathrm{H}\( (atomic mass \)=1.00783 \mathrm{u}\(; abundance \)\left.99.9885 \%\right)\( and \){ }^{2} \mathrm{H}\( (atomic mass \)=2.01410 \mathrm{u}$; abundance \(\left.0.0115 \%\right)\). (a) How many peaks will the mass spectrum have? (b) Give the relative atomic masses of each of these peaks. (c) Which peak will be the largest, and which the smallest?

Complete the table by filling in the formula for the ionic compound formed by each pair of cations and anions, as shown for the first pair. $$ \begin{array}{c|c|c|c|c} \hline \text { Ion } & \mathrm{Na}^{+} & \mathrm{Ca}^{2+} & \mathrm{Fe}^{2+} & \mathrm{Al}^{3+} \\ \hline \mathrm{O}^{2-} & \mathrm{Na}_{2} \mathrm{O} & & & \\ \mathrm{NO}_{3}^{-} & & & & \\ \mathrm{SO}_{4}^{2-} & & & & \\ \mathrm{AsO}_{4}{ }^{3-} & & & & \\ \hline \end{array} $$
