Transcript: Neon Sean Griffin 12/11/17 P.1 Neon Neon is a non-metal on the periodic table. It has an atomic number of 10 and an atomic mass of 20. At room temperature, neon is a colorless gas. Located in period 8A, neon is a noble gas. What is Neon? P=10 N=10 What is a Noble Gas? On the periodic table, period 8A is known as the Noble Gases. In the past, these were known as the rare or inert gases. Inert means "low reactivity." Noble gases were thought to have low reactivity because they did not react with any tests that the scientists made. The reason for this is the fact that the noble gases' electron cloud is full. As my old teacher once said, "Noble gases are just what they sound like, Noble. They have all the money/electrons that they could ever want, and don't want to ascosiate with commoners." One of the most popular uses of neon is in a neon sign. While neon is the most popular, pure neon can only give off a bright red glow. In order to make the rainbow of colors that are used in signs, makers use all of the noble gases. Other than signs, neon has no biological role and is non-toxic. Uses of Neon Neon was discovered by Sir William Ramsay and Morris Travers in 1898. Neon is the 5th most abundant element in the universe, but only makes up 0.0018% of our atmosphere. The element was named after the greek word "neos" which means New. Who Discovered Neon?
