P6+-+Noble+Gasses

Our group is studying Group 18 in the periodic table. This group is called the Noble Gases. There are six elements that are classified in the noble gases' group, these elements are Helium, Neon, Argon, Krypton, Xenon, and Radon. These elements were once considered inert gases until the 1960's, because they had an oxidation number of zero, which prevents the noble gases from forming compounds immediately. All noble gases have the maximum number of electrons possible in their outer shell, which makes them stable. The elements in the noble gases' group are gases. Three physical properties of noble gases are their color (when they are heated), they have a low boiling point, and no odor. Three chemical properties of noble gases are that it has high ionization energies, it is fairly none reactive, and it has the ability to change color when it is heated. Noble gases have many interesting facts. One is that some noble gases are used in neon lighting, the neon gas in the bulb are heated, giving the light different colors. Another noble gas used is krypton. Krypton is used in comercial light bulbs. Argon is used in the light bulbs to make the filiment react to the spark. Cited Sources:
