It’s Elementary — March MadnessMarch Madness is upon us! Your students are probably already working on their next assignment in bracketology, predicting

the field for the NCAA Basketball Tournament. (Although the word doesn’t appear in Webster’s, there, is an article on bracketology on Wikipedia, so it must be real.) Let’s apply the principles of bracketology to the properties of the elements. The competitionamong the 64 elements is stiff, and there is a wealth of information for students to research, in this “elementary” version of MarchMadness!

Review of Element Properties

Define each of the following properties of the elements and briefly describe any periodic trend in the property across a row ordown a column in the periodic table.

• Ionization energy • Atomic radius

Tournament Rules

Here are the rules for predicting the winners in each round of It’s Elementary—March Madness. In the event of a tie in theproperties of two competing elements in any round of the tournament, the element with the larger atomic mass always wins.

• First round: Research the date of dricovery of each element. In each bracket, the element that was discovered earlier (inits free elemnentforin) wins and proceeds to the second round. If an element has been known since ancient times, assign ita discovery date of zero.

• Second round: Compare the ionization energy of the elements in each bracket. The element with the, higher ionizationenergy is the winner and advances to the Sweet 16.

• Third round (Sweet 16): Compare the group numbers of the elements—the winner is the element with the larger groupnunzber using the international (‘JUPAC) system (Groups 1-.-18).

• Fourth round: The element with the larger atomic radius wins this round and earns a trip to the Final Four. Use theatomic or covalent radius only, not the van der Waa]s radius.

• Semifinals (Final Four): Solve the following riddles to determine the two elements that will compete for the championship.

+ This “salt-maker” is also a rainmaker when its silver salt is scattered into clouds.•. Once a sedative and cure for nervous tension, the ion of this’ element is now a trite or commonplace ‘expression.

• Finals: It’s often said that there’s no ______ in team, but it is the winner in this field!

Sweet 16 Chemistry of Gases TournamentDo your students eagerly compete to fill out their “March Madness” tournament brackets? Have some fun and inspire your

students with March Madness chemistry! This activity combines the popularity of “bracketology” with a review of the preparationand properties of common gases. The historical foundation of modem chemistry was built on the study of gases, such as experiments with hydrogen and oxygen in the 18th century that led to the modern definition of an element versus a compound. Fromthese historical roots, the study of gases continues to influence our lives. The role of “greenhouse gases,” in particular, remains avital area of research—and may help determine the winner of the Sweet 16 Chemistry of Gases tournament!

Review of Concepts

• Common gases • Acid—base properties Ideal gas law

• Solubility of gases in water • Molar volume of gases at STP • Greenhouse gases

Tournament Rules

The rules for tilling out the tournament bracket are summarized below. A supplementary chemical reactions worksheet hasbeen provided to help identify the contestants in the Sweet 16 Chemistry of Gases tournament.

• First round: Predict the name and formula of the gaseous product obtained in a chemical reaction involving the reactantslisted in the first round. The gas “escapes” to the second round!

• Second round: Compare the solubility of the gases in water. The winner is the gas that dissolves in water to form an acidicsolution.

• Semifinals: Calculate the density of each gas in gIL based on its molar mass (g/mole) and the molar volume of an ideal gasat STP (22.4 LImole). The winner is the gas that is more dense.

• Final: The winner of the tournament is a “greenhouse gas” that is produced in large quantities in volcanic emissions.
