NOBLE GASES

NOBLE GASES BASICS

• Located on the far right side of the PT
• 6 noble gases in total
• Full valence shells = relatively non-reactive
• Extremely rare in nature
• They are referred to as "inert gases"

PHYSICAL/CHEMICAL PROPERTIES

• Colorless, tasteless&nonflammable
• All gases in standard temp.
• Low boiling points and melting points
• Not good CONDUCTORS (electr.)
• Stable with a narrow liquid range

HELIUM

• Boiling point = -457.6°F
• Melting point = -451.48°F
• Density = 0.1786 g/cm³
• Uses = balloons&deep sea diving
• Completely non-reactive

KRYPTON

• Boiling point = -244.12°F
• Melting point = -251.2°F
• Density = 3.74 g/cm³
• Uses = lightning (occurrence)
• Can become a solid with fluorine

ARGON

• Boiling point = -302.8°F
• Melting point = -308.74°F
• Density = 1.784 g/cm³
• Uses = common lightbulbs
• Non-reactive

NEON
