Neon is a chemical element; it has the symbol Ne and atomic number 10. It is the second noble gas in the periodic table. [13] Neon is a colorless, odorless, inert monatomic gas under standard conditions, with approximately two-thirds the density of air.
Chemical Characteristics. Neon is chemically inert gas. It is identified as most electronegative element based on Allen electronegativity scale. Its triple point, the point at which the three phases of a substance coexist in thermodynamic equilibrium, is 24.5561 K (248.5 degree Celsius).
neon (Ne), chemical element, inert gas of Group 18 (noble gases) of the periodic table, used in electric signs and fluorescent lamps. Colourless, odourless, tasteless, and lighter than air, neon gas occurs in minute quantities in Earth’s atmosphere and trapped within the rocks of Earth’s crust.
8 Απρ 2023 · Chemical Properties of Neon. Neon is a chemically inactive element. Thus yet, no other element or chemical has been able to react with Ne. The most stable or inert atoms have 8 electrons in their outer shell. Because of their exceedingly low chemical reactivity, they are referred to as inert gases.

Overview. Neon is a member of the noble gas family. Other elements in this family includes helium, argon, krypton, xenon, and radon. These gases are in Group 18 (VIIIA) of the periodic table. The periodic table is a chart that shows how chemical elements are related to each other. The noble gases are sometimes called the inert gases.
