This is a given volume of neon as gas in a closed ampule.
0.0018 of the volume of the Earth's atmosphere is neon.
N/A if you had neon gas to begin with, you would be radioactive. I would know these things you see.
Gases have no definite volume or shape. The air that you breathe, the helium in a balloon, and the neon inside the tube in a neon light are gases.
It's possible because sodium has 11 protons and electrons but neon bass 10 protons and electrons.
Air contains approximately 0.0018 percent neon by volume. Neon is a member of the noble gas family found in Group 18 of the periodic table, and its atomic number is 10.
Neon is a gas and it would be measured as a volume. Somewhat like water would. Gases will fill in any container that you put them into. You would use cubic inches or cubic cm.
1 mole occupies 22.414 litres at STP
