Quiz Answer Key and Fun Facts

1. What is the heaviest of the naturally-occurring Noble gases?

Answer: Radon

Element 118 has been produced artificially and would fall under the Noble gas column.

2. What is the lightest element of the ones below with an atomic symbol that is also a US state postal code?

Answer: Aluminum (AL)

Others include: molybdenum (MO), indium (IN), lanthanum (LA), neodymium (ND), protactinium (PA), mendelevium (MD), meitnerium (MT) and flerovium (FL). Neon (NE), for Nebraska, is lighter than aluminum, but I didn't put it in the list intentionally.

3. The heaviest element with a one letter atomic symbol is:

Answer: Uranium

4. Name one of the four elements named after Ytterby, a village in Sweden near Vauxholm.

Answer: yttrium

Ytterby is the site of a quarry which yielded many unusual minerals containing rare earths and other elements.

5. What is the lightest element, by atomic mass, with an atomic symbol not related to its English name?

Answer: Sodium (Na)

Hydrogen, at 1.0079, is the lightest of all the elements. Sodium is 22.9897, potassium is 39.0983, iron is 55.845 and tungsten is 183.84.

9. What element's three isotopes have different names?

Answer: Hydrogen

The ordinary isotope of hydrogen, H, is known as Protium, the other two isotopes are Deuterium (a proton and a neutron) and Tritium (a protron and two neutrons). Deuterium and Tritium are both used as fuel in nuclear fusion reactors. One atom of Deuterium is found in about 6000 ordinary hydrogen atoms.

10. What element is named after Copenhagen, Denmark?

Answer: Hafnium

Hafinia, Latin name for Copenhagen

11. Which element has close to 10,000,000 known compounds?

Answer: Carbon

Carbon is unique among the elements in the vast number and variety of compounds it can form. With hydrogen, oxygen, nitrogen, and other elements, it forms a very large number of compounds, carbon atom often being linked to carbon atom. There are close to ten million known carbon compounds, many thousands of which are vital to organic and life processes.

12. It was not a good idea to invest in this gas in the early 20th century. Its price went from $2500 per cu. ft. (1915) to 1.5 cents per cu. ft. (1940)

Answer: Helium

The U.S. Bureau of Mines has set the price of Grade A helium at $37.50 per 1000 cu ft in 1986.

13. What is one of the two most abundant elements in the universe?

Answer: hydrogen

Top of the chart. 8-)

14. Mendeleev's version of the periodic table was first published in which century?

Answer: Nineteenth

In 1869.
