At room temperature, neon, which is an inert gas, is far and away less dense than water. Water, as you know, is a liquid at room temperature, and neon is never found in nature on earth as anything but a gas. A link can be found below.
Helium and neon are less dense than air; argon, krypton, xenon and radon are denser than air.
Neon, ammonia, methane, hydrogen, helium and water vapour are the best lifting gases and are all less denser than air.
Yes, neon is lighter than lead. Neon has an atomic number of 10 and an atomic mass of about 20.18 atomic mass units (amu), while lead has an atomic number of 82 and an atomic mass of approximately 207.2 amu. Therefore, neon is significantly less dense than lead.
The atomic weight of neon is 20.180 amu, or atomic mass units.
Neon gas has a very low density compared to other elements. It is lighter than air and is around 0.9 times as dense as air.
Xenon is an inert gas; it is colorless, odorless and nontoxic. It is denser than helium, neon, and argon, but not as dense as radon.
Neon is a nonreactive gas. As it is a gas, it would only be found naturally (on earth) as a liquid if it were cooled down a LOT. There is no gas that is more dense than a liquid. Also, being nonreactive, neon doesn't bond with other elements without a LOT of energy, and even then, it is extremely unstable, so it would almost always be found as a gas. So, neon would be found in the air, or in gas pockets underground.
When neon is exposed to heat, it remains in its gaseous state because it is a noble gas with a very low boiling point of -246.08°C (-410.94°F). Heating neon increases the kinetic energy of its atoms, leading to a rise in temperature and pressure if contained. However, unlike reactive gases, neon does not undergo any chemical reactions or changes in its atomic structure when heated. Instead, it simply expands and becomes less dense.
Neon in German is - Neon (!) Neon tube is Neonröhre
The lightest element that is in period number 2 is lithium. Lithium is also the solid that is the least dense.
