a. \(\left({ }_{8}^{17} \mathrm{O}\right)\) b. \(\left({ }_{17}^{37} \mathrm{Cl}\right)\) c. \(\left({ }_{27}^{60} \mathrm{Co}\right)\) d. \(\left({ }_{26}^{57} \mathrm{Fe}\right)\) e. \(\left({ }_{53}^{131} \mathrm{I}\right)\) f. \(\left({ }_{3}^{7} \mathrm{Li}\right)\)

Step by step solution

01

Determine Element and Mass Number

The atomic number Z is 8, which corresponds to Oxygen (O), and the number of neutrons is 9. To find the mass number A, we add the number of protons and neutrons: A = 8 + 9 = 17.
02

Write Atomic Symbol for Oxygen Isotope

Using the determined element and mass number, we can write the atomic symbol as: \(\left({ }_{8}^{17} \mathrm{O}\right)\). #b. the isotope of chlorine in which A = 37#
03

Determine Element and Atomic Number

The element is Chlorine (Cl) with a mass number A = 37. The atomic number Z for Chlorine is 17.
04

Write Atomic Symbol for Chlorine Isotope

Using the given element and mass number, we can write the atomic symbol as: \(\left({ }_{17}^{37} \mathrm{Cl}\right)\). #c. Z = 27, A = 60#
05

Determine Element

The atomic number Z is 27, which corresponds to Cobalt (Co).
06

Write Atomic Symbol for Cobalt Isotope

Using the given element, atomic number, and mass number, we can write the atomic symbol as: \(\left({ }_{27}^{60} \mathrm{Co}\right)\). #d. number of protons = 26, number of neutrons = 31#
07

Determine Element, Atomic Number, and Mass Number

The number of protons is 26, which corresponds to the element Iron (Fe) with the atomic number Z = 26. The number of neutrons is 31. To find the mass number A, add the number of protons and neutrons: A = 26 + 31 = 57.
08

Write Atomic Symbol for Iron Isotope

Using the determined element and mass number, we can write the atomic symbol as: \(\left({ }_{26}^{57} \mathrm{Fe}\right)\). #e. the isotope of I with a mass number of 131#
09

Determine Element and Atomic Number

The element is Iodine (I) with a mass number A = 131. The atomic number Z for Iodine is 53.
10

Write Atomic Symbol for Iodine Isotope

Using the given element and mass number, we can write the atomic symbol as: \(\left({ }_{53}^{131} \mathrm{I}\right)\). #f. Z = 3, number of neutrons = 4#
11

Determine Element and Mass Number

The atomic number Z is 3, which corresponds to Lithium (Li), and the number of neutrons is 4. To find the mass number A, we add the number of protons and neutrons: A = 3 + 4 = 7.
12

Write Atomic Symbol for Lithium Isotope

Using the determined element and mass number, we can write the atomic symbol as: \(\left({ }_{3}^{7} \mathrm{Li}\right)\).

Carbon- 14 dating is a method used to determine the age of historical artifacts by examining the ratio of two isotopes of carbon (carbon- 14 and carbon-12). A living plant consumes carbon dioxide in the photosynthesis process and incorporates the carbon, including \({ }^{14} \mathrm{C}\), into its molecules. As long as a plant lives, the \({ }^{14} \mathrm{C} /{ }^{12} \mathrm{C}\) ratio in its molecules remains the same as in the atmosphere because of its continuous uptake of carbon. However, as soon as a tree is cut to make a wooden bowl or a flax plant is harvested to make linen, the \({ }^{14} \mathrm{C}^{12} \mathrm{C}\) ratio begins to decrease because of the radioactive decay of \({ }^{14} \mathrm{C}\left({ }^{12} \mathrm{C}\right.\) is stable). By comparing the current \({ }^{14} \mathrm{C} /{ }^{12} \mathrm{C}\) ratio to the presumed ratio when the artifact was made, one can estimate the age of the artifact. For carbon-14 and carbon- 12 , how many protons and neutrons are in each nucleus? Assuming neutral atoms, how many electrons are present in an atom of carbon- 14 and in an atom of carbon-12?

A chemist in a galaxy far, far away performed the Millikan oil drop experiment and got the following results for the charges on various drops. Use these data to calculate the charge of the electron in zirkombs. \(2.56 \times 10^{-12}\) zirkombs \(\quad 7.68 \times 10^{-12}\) zirkombs \(3.84 \times 10^{-12}\) zirkombs \(\quad 6.40 \times 10^{-13}\) zirkombs

Give the names of the nonmetals that correspond to the following symbols: As, I, Xe, He, C, Si.

You have two distinct gaseous compounds made from element \(\mathrm{X}\) and element \(\mathrm{Y}\). The mass percents are as follows: Compound I: \(30.43 \% \mathrm{X}, 69.57 \% \mathrm{Y}\) Compound II: \(63.64 \% \mathrm{X}, 36.36 \% \mathrm{Y}\) In their natural standard states, element \(\mathrm{X}\) and element \(\mathrm{Y}\) exist as gases. (Monatomic? Diatomic? Triatomic? That is for you to determine.) When you react "gas X" with "gas Y" to make the products, you get the following data (all at the same pressure and temperature): 1 volume "gas \(\mathrm{X}^{\prime \prime}+2\) volumes "gas \(\mathrm{Y}^{\prime \prime} \longrightarrow\) 2 volumes compound \(I\) 2 volumes "gas \(\mathrm{X}^{\prime \prime}+1\) volume "gas \(\mathrm{Y}^{\prime \prime} \longrightarrow\) 2 volumes compound II Assume the simplest possible formulas for reactants and products in the chemical equations above. Then, determine the relative atomic masses of element \(\mathrm{X}\) and element \(\mathrm{Y}\).
