Some elemental names are ancient and of murky origin. Other names capture the chemical nature of the elements’ color or reactivity. More recently named elements tend to mirror the place where they were discovered or the people who discovered them. In this activity students will review the origin of the names of the chemical elements, read about recent controversies in naming new elements, and finally, suggest new, alternative names for some chemical elements, based on their history, chemical characteristics, or uses. Background The development of chemical knowledge is mirrored by our understanding of the elements. Beginning with the realization that elements are fundamental building blocks of nature, and continuing with the discovery of every new element—we see that as our knowledge of elements has grown, so has our understanding of nature. Traditionally, the honor of naming new elements went to their discoverers. The names, which have been selected over the decades, often show a deep knowledge of classic history and literature. Greek and Roman gods account for several names and other elemental names are based on ancient classical languages. Some of the discoverers found clever ways to illustrate the chemical characteristics of the elements or the circumstances of discovery in the names they chose. For example, the name “bromine” refers to the element’s strong, objectionable odor, while lanthanum was named after the Greek term “to lie hidden.” There has also been a fair amount of boosterism in naming elements, giving honor to the discoverer’s country, state, or hometown. For instance, the small Swedish town of Ytterby has no fewer than four elements named in its honor, by virtue of having a gravel pit on its outskirts that yielded the raw material from which these elements were isolated. In this activity, students get to play the role of discoverer and suggest new names for elements, as though they had just been discovered. It will be interesting to see if students can be as clever and insightful as the original scientists who named the elements. Getting Ready If this activity is to be done during class time, you will need to gather references or resource materials so students can research the history, characteristics, and uses of the elements. Doing This Activity 1. Ask students if they know the origin of any element’s name. This discussion can include information students have from past experience, as well as students’ conclusions about some of the more obvious associations. Students may realize that berkelium is named for Berkeley, CA, but not know why. Use this discussion to bring out some of the fine points behind the names of the elements. 2. Provide students with information on the derivations of the names of the elements. The student handout may serve as a good reference. 3. Assign each student from one to three elements to study and research. Students should gather information on the history of the elements’ discoveries, including who discovered each element. They 65 Name: _____________________________ Student ID Number: __________________ Period: ______ Date: ______________________ should also research the chemical properties and the uses of their elements. Students will use this information to suggest a new name for each element to which they have been assigned. The new name should be based on some part of the information they learned about the element. Use the student handout provided to help students organize their research. 4. Each student will prepare one to three squares for a periodic table based on the new elemental names the class has created. Using a 3 x 5 inch card, have students write the traditional atomic number and symbol of their element. Below the traditional symbol, they should write the new name they have assigned to the element, along with a short paragraph describing why they have chosen that name. 5. Assemble all the new elemental names on a bulletin board or wall in the shape of a periodic table, so all students can see the results of what their classmates have done. Optional Extension Give students the opportunity to learn more about the names of the elements. Using the information from the list of “Origins of the Names of the Chemical Elements” as a starting point, have students add to and elaborate on the brief descriptions of the origin of the name from the Student Page. Assessment Opportunity Ask students to write a brief essay on the five elements they believe have the most fitting or appropriate name. 66 Name: _____________________________ Student ID Number: __________________ Period: ______ Date: ______________________ Student Handout Name of my element: History of the discovery of this element: Chemical characteristics of this element: Some common uses of this element: My new name for this element: The reason I chose this name: 67
