Ne-20


 * Neon**

Neon's form of matter is a gas, and it is an element that is mainly used for different types of lighting. It was discovered in 1898 by Sir William Ramsay. The element symbol for neon is ne, its atomic number is 10, and its atomic mass is 20. Neon is a noble gas, and a noble gas is an Inert gas that has the most possible electrons in outer most shell, making it stable. The density of neon is 0.901 grams per cubic centimeter, therefore it will float in water. Neon has 10 electrons, 10 protons, and 10 neutrons.
