Chapter 2: Problem 23

The following radioactive isotopes have applications in medicine. Write their symbols in the form \(\&\) E. (a) cobalt- \(60 ;\) (b) phosphorus- \(32 ;\) (c) iron-59; (d) radium-226.

Short Answer

Expert verified
Isotopic symbols are: \(_{27}^{60}Co\), \(_{15}^{32}P\), \(_{26}^{59}Fe\), and \(_{88}^{226}Ra\).

Step by step solution

01

Write the symbol for Cobalt-60

Cobalt (Co) has an atomic number of \(27\) and its isotopic mass is given as \(60\). Hence, the symbol for Cobalt-60 is \(_{27}^{60}Co.
02

Write the symbol for Phosphorus-32

Phosphorus (P) has an atomic number of \(15\) and its isotopic mass is given as \(32\). Hence, the symbol for Phosphorus-32 is \(_{15}^{32}P.
03

Write the symbol for Iron-59

Iron (Fe) has an atomic number of \(26\) and its isotopic mass is given as \(59\). Hence, the symbol for Iron-59 is \(_{26}^{59}Fe.
04

Write the symbol for Radium-226

Radium (Ra) has an atomic number of \(88\) and its isotopic mass is given as \(226\). Hence, the symbol for Radium-226 is \(_{88}^{226}Ra.

How many atoms are present in a \(75.0 \mathrm{cm}^{3}\) sample of plumber's solder, a lead-tin alloy containing \(67 \% \mathrm{Pb}\) by mass and having a density of \(9.4 \mathrm{g} / \mathrm{cm}^{3} ?\)

Monel metal is a corrosion-resistant copper-nickel alloy used in the electronics industry. A particular alloy with a density of \(8.80 \mathrm{g} / \mathrm{cm}^{3}\) and containing \(0.022 \%\) Si by mass is used to make a rectangular plate \(15.0 \mathrm{cm}\) long, \(12.5 \mathrm{cm}\) wide, \(3.00 \mathrm{mm}\) thick, and has a \(2.50 \mathrm{cm}\) diameter hole drilled through its center. How many silicon- 30 atoms are found in this plate? The mass of a silicon- 30 atom is \(29.97376 \mathrm{u}\) and the percent natural abundance of silicon- 30 is 3.10\%.

When an iron object rusts, its mass increases. When a match burns, its mass decreases. Do these observations violate the law of conservation of mass? Explain.
