Neon Need-to-knows
Neon- Origin from Greek word (neos) meaning new
Ne
Atomic # 10
Atomic Mass- 20.1797 amu
Group 18 Period 2
1s2 2s2 2p6 Valence Electrons-8
Color- Colourless
Melting Point= - 248.6 C
Boiling Point= -246.1 C
Density (at 293 K) = 0.901 g/cm3
Structure- Cubic
Physical State (at room temperature)- gas
Atomic Radius- .848 pm
Neon is a simple asphyxiant and, if the area is not properly ventilated, the oxygen in the air gets displaced and the user may suffocate.
Today, neon is mostly used for bright street signs, neon lasers, and tv tubes but, neon glow lamps were very common in the 1970s
