Group 0

Recall the simple, defining physical and chemical properties of the Group 0 elements.

Explain how the observed properties of Group 0 elements depend on their stable outer shell of electrons.

Identify Group 0 elements as the noble gases and explain their unreactive nature and inability to easily form molecules due to their full, stable outer electron arrangements.

Recall that all noble gases possess eight electrons in their highest energy level, with the exception of helium, which possesses two.

Predict the physical properties of noble gases from given trends, noting that their boiling points increase down the group as relative atomic mass increases.
