There are "noble gases" of which neon is one. They're the elements at the far-right side of the Periodic Table. As their outer orbitals are completely populated, noble gases are nonreactive.
Neon is chemically inert and does not combine with other elements (including itself). It exists as a mono atomic gas.
Guppies will eat neons tetra babies but are not large enough to eat fully grown neons.
Neon (the gas) is an element. Elements are pure, they are not made out of other things. For instance the gas Carbon Dioxide is a compound made Carbon and Oxygen, but Carbon and Oxygen are elements and are not made out of anything else.
The oxidation number of Neon is 0. It does not want to gain or lose any electrons. It already has a full octet, therefore it remains at 0.
no it is a gas
it is a cucumber
no.
Not for long. The neons would be eaten pretty quickly.
That engine is only in the Neons.That engine is only in the Neons.
it is nonmetal
it smell's bad
Generally no. Depending on the local police department, they MAY permit neons.
