Noble Gases - The Gases In Group 18

This video tutorial explores noble gases, which are group 18 elements known for their full valence electron shells, making them stable and mostly non-reactive. The tutorial covers their properties, such as being colorless and monotonic, and their increasing boiling points and densities down the group. It also highlights various applications, including helium in balloons, xenon in car headlights, and radon in radiotherapy. The video concludes with advanced uses like krypton in insulation and xenon in satellite propulsion.

What are the noble gases and what are their common properties?

Explain why noble gases are considered stable elements.

How does the size of noble gas atoms affect their boiling points?

Describe some practical applications of noble gases in everyday life.

What is the significance of radon in medical applications?
