Background For Teachers:
Today, the symbols for elements are derived from the elements' name. the names come from many sources. Most are named by the person credited with discovering the element. For example, two elements were discovered by Ellen H. Richards, a scientist who founded the home economics profession. As the discoverer, she would have had the right to name those elements.
Names sometimes honor a place or a person. Curium, for example, is a radiative element named to honor Marie Curie, the scientist who discovered radium. Hafnium is named for the place it was discovered, Copenhagen. The Latin name for Copenhagen was Hafnia. Sodium was named for one of its common compounds, soda. Soda was commonly used as a headache remedy and the Arabic word for headache was soda, hence soda and sodium.
The most common source of an element name is some property of the element. Protactinium, for
example, is a radioactive element that decays to actinium. Porotos, in Greek, means first.
Protactinium means first before actinium. Likewise, in Swedish tung means heavy and sten means
stone, so tungsten means heavy stone.
Intended Learning Outcomes:
The students will take a PREASSESSMENT quiz to determine their current knowledge
about abbreviations for chemical elements.
