Neon--Ne

Neon is the tenth element on the periodic table, and it is the first of the noble gases to have a full 8-electron orbital. Neon produces a reddish color on "neon" lights, and is completely inert, so it has no electronegativity. At STP, neon is gaseous and has a density of 0.900 g/L. Ne melts at 24.55 K and boils at 27.10 K. The atomic mass of Ne is 20.1797, and its electron configuration is 1s²2s²p⁶.
