You will get to learn about the major groups of elements found in the Periodic Table and their properties. Gain further understanding of how the structure of the Periodic Table can help you see trends in the properties of elements.
After completing this tutorial, you will be able to complete the following:
What properties do all the elements in Group 8A share?
~ Known as the noble gases, all of the elements in Group 8A are colorless, odorless, and monatomic gases.
What unique characteristic makes helium the coldest liquid refrigerant available?
~ Helium is the coldest liquid refrigerant available because it has the lowest boiling point of any substance on Earth.
What color glow does neon emit when it is used inside a discharge tube?
~ Neon emits a reddish-orange glow when it is used inside a discharge tube.
Which element in Group 8A is sometimes used as an affordable alternative to nitrogen?
~ Argon is sometimes used as an inexpensive alternative to nitrogen when nitrogen is not inert enough for a particular use.
