  3. Today’s activities • notes • Read A.4 p. 114 • Complete the A.4 supplement I can explain how elements on the periodic table got their names

  4. I can explain how elements on the periodic table got their names notes • The names of the chemical elements are a reflection of their history. 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.

  5. I can explain how elements on the periodic table got their names notes • 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.

  6. I can explain how elements on the periodic table got their names notes • 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.”

  7. I can explain how elements on the periodic table got their names notes • 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.

  8. Recent updates I can explain how elements on the periodic table got their names • 118 elements • #110 = Darmstadtium • #111 = Roentgenium • #114 = Flevovium • Corucopium # 112 added in 2011 • 5 more to be named (113,115,116,117,118) • #119 and up have yet to be made.

  9. I can explain how elements on the periodic table got their names A.4 Supplement • Pick a number between 1-20 • Pick a number between 21-111 • Complete the worksheet by researching on the internet

  10. Cool down • Explain the origin of the names of at least 3 elements I can explain how elements on the periodic table got their names
