Neon [Ne] – Element Details, History, Atomic Structure, Facts, Properties, Electronic Configuration, Atomic Spectrum, Uses
Element 10 of Periodic table is Neon with atomic number 10, atomic weight 20.1797. Neon, symbol Ne, has a Face Centered Cubic structure and Colorless color. Neon is a noble gas element. Trivial name of Neon is noble gases*, aerogens. Know everything about Neon Facts, Physical Properties, Chemical Properties, Electronic configuration, Atomic and Crystal Structure.
History of Neon
The element Neon was discovered by Morris Travers in year 1898 in United Kingdom . Neon derived its name from the Greek neos, meaning ‘new’
Neon is a chemical element with symbol Ne and atomic number 10. It is in group 18 (noble gases) of the periodic table. Neon is a colorless, odorless, inert monatomic gas under standard conditions, with about two-thirds the density of air.
How to Locate Neon on Periodic Table
Periodic table is arranged by atomic number, number of protons in the nucleus which is same as number of electrons. The atomic number increases from left to right. Periodic table starts at top left (atomic number 1) and ends at bottom right (atomic number 118). Therefore you can directly look for atomic number 10 to find Neon on periodic table.
Another way to read periodic table and locate an element is by using group number (column) and period number (row). To locate Neon on periodic table look for cross section of group 18 and period 2 in the modern periodic table.
Neon Atomic Structure and Orbital Properties
Neon atoms have 10 electrons and the electronic shell structure is [2, 8] with Atomic Term Symbol (Quantum Numbers) 1S0.
Atomic Structure of Neon
Ground State Electronic Configuration of Neon - neutral Neon atom
The ground state electronic configuration of Neutral Neon atom is [He] 2s2 2p6. The portion of Neon configuration that is equivalent to the noble gas of the preceding period, is abbreviated as [He]. For atoms with many electrons, this notation can become lengthy and so an abbreviated notation is used.This is important as it is the Valence electrons 2s2 2p6, electrons in the outermost shell that determine the chemical properties of the element.

Use of Neon
Neon is also used to make high-voltage indicators and switching gear, lightning arresters, diving equipment and lasers. Liquid neon is an important cryogenic refrigerant. It has over 40 times more refrigerating capacity per unit volume than liquid helium, and more than 3 times that of liquid hydrogen.
