The seventh noble gas is ununoctium, though it is also called eka-radon or simply element 118. It is a synthetic element that scientists created in the lab. It is radioactive and unstable, so it degrades quickly- within minutes. Because of this, its properties have not been observed extensively. However, some scientists theorize that though ununoctium is in Group 18 of the Periodic Table-- the group for noble gases-- it may not in fact be a noble gas. Calculations indicate that this element may be a solid at room temperature.

The second noble gas is Neon (Ne). The noble gases are chemical elements with similar properties: they are odorless, colorless, monatomic gases with low chemical reactivity except under particular conditions. Neon has about 2/3 the density of air, it is chemically inert, and it forms no uncharged chemical copounds. It has a bright orange-red glow when placed in a high voltage electric field, which is why it is used in glow lamps or advertising signs.

"Noble gas configuration" means that in writing out an electron configuration for an atom, rather than writing out the occupation of each and every orbital specifically, you instead lump all of the core electrons together and designate it with the symbol of the corresponding noble gas on the periodic table (in brackets). For example, the noble gas configuration of phosphorus will be [Ne]3s23p3
no. it is a molecule, not a noble gas
A noble gas is colorless.
Neon is a noble gas.
