Neon has 8 more protons and 8 more electrons than helium. It's heavier, but still lighter than air.
Helium is lighter than neon and will diffuse faster than neon.
No. The molar mass of dry air is 28.97 g/mol. Noble gases are monatomic, so their atomic mass represent their molar mass. From this we can tell that helium and neon are less dense (lighter) than air, while argon (atomic mass 39.9) onwards are denser than air.
Because lighter and heavier refer to an objects weight - which has nothing to do with density ! For example - a kilo of feathers is heavier than half a kilo of lead - but lead is more dense !
Lead is the denser element
No. Neon is lighter than iron

Neon
yes because lead is heavier than steal.
No, lead is more dense than aluminium.
Neon has 8 more protons and 8 more electrons than helium. It's heavier, but still lighter than air.
Yes
No. Gaseous diffusion is a function of mass, with lighter molecules diffusing more rapidly. Neon (approximate atomic mass of 20) is considerably lighter than nitrogen dioxide (approximate molecular mass 46).
Helium is lighter than neon and will diffuse faster than neon.
It isn't. How did you get that idea? Ice is much lighter than lead, for the same volume.
Yes there is why?
The fuse for the cigarette lighter on a 2004 Dodge Neon is under the hood. It is fuse #14 in the power distribution center.
