Group 18
Noble gases are nonmetals that are not reactive and are in Group 18 on the periodic table. Noble Gases include Helium, Neon, Argon, Krypton, Xenon, and Radon. Lightbulbs filled with argon last longer than normal light bulbs without argon in them. Helium has a low density and makes blimps, weather balloons and many other things float. All of these elements do not naturally form chemical bonds with other atoms and are almost always found in their purest state. The xenon lights in cars can hurt people’s eyes but are not harmful in any way. Krypton is one of the rarest gases on Earth, composing only 1 part per million in the atmosphere by volume.

ReplyDeleteArgon is am element that has the atomic number of 18 and the atomic mass of 39.9. The chemical symbol is Ar.
ReplyDeleteHelium has a colorless,odorless,tasteless non-toxic gas.The atomic number is 2. Helium's boiling point is the lowest boiling point out of all the elements on the periodic table!
