Why Neon Matters
Neon helps connect atomic number 10, noble gas behavior, period 2 trends, and electron shell structure. Its gas phase, atomic mass of 20.18 u, and electron configuration 1s² 2s² 2p⁶ make it useful for comparing bonding patterns across the periodic table.
Discovery and Occurrence
Neon was discovered 1898 by Morris Travers, William Ramsay. Neon is a chemical element with symbol Ne and atomic number 10. It is a noble gas, colorless, odorless, inert monatomic gas under standard conditions.
Safety and Handling Context
Neon is a noble gas and is generally chemically inert. The main safety concern for many gases is displacement of breathable air in confined spaces.
