Slide2Group 18- The Noble Gases
Noble gases make up a group of chemical elements with similar propertiesThe properties include being odorless, colorless, low chemical reactivity, and are monatomic gases.Their outer shell of valence electrons is considered to be “full”, which gives them little tendency to participate in chemical reactionsWeak interatomic forceLow melting and boiling points
Slide3The Elements
The six noble gases that occur naturally are Helium, Neon, Argon, Krypton, Xenon, and Radon. ElementNumber of electronsHelium2

Slide4Noble gases do not form ions because they already have the perfect number of electrons in their topmost energy levels
Incapable of reacting with other elements under room temperature
