LiveScience: How Many Chemical Elements Can You Name?

Science History Institute survey shows one in five Americans can’t name one.

Time for a science refresher course? One in five Americans can't name a single element on the periodic table.

Most Americans surveyed (59 percent) couldn't name more than 10 elements of the 118 that grace the periodic table. The new survey (“Rare Earth Elements and Why they Matter: The Importance of Understanding the Elements of Technology”), which comes courtesy of Philadelphia-based nonprofit the Science History Institute, also drives home a dearth of understanding of rare earth elements. Twenty-six percent of those surveyed had not heard this term, and 35 percent had heard it, but had no idea what it meant.
