Both are noble gases, have completely filled valence orbitals and hence are stable and chemically inert.
The lasing material in a helium-neon laser is a mixture of helium and neon gases. The neon gas is responsible for emitting the red laser light when excited by the helium gas.
Helium, neon, and argon are the three lightest members of the noble gases.
No, helium is not used in neon signs. Neon signs are filled with neon gas, which produces the iconic red glow when an electric current is passed through it. Helium is a colorless and odorless gas often used for filling balloons and as a coolant in some applications.

The element with a mass of less than 30 and is a noble gas is Neon (Ne). Neon has an atomic mass of around 20.18 and is a colorless, odorless gas commonly used in neon signs due to its bright red-orange glow when electrified.

because the size of helium is smaller than that of neon.

Depends on the purpose. But if you combine neon with helium, and obtain a helium-neon laser, you can see that it is much smaller than a xenon laser.
The element with a mass of less than 30 and is a noble gas is Neon (Ne). Neon has an atomic mass of around 20.18 and is a colorless, odorless gas commonly used in neon signs due to its bright red-orange glow when electrified.
Neon is not the first noble gas; helium is.
The first four are (in order of increasing number / mass: He = Helium, Ne = Neon, Ar = Argon, Kr = Krypton Xe = Xenon and Ra = Radon are the other two noble gases
The typical ratio of helium (He) to neon (Ne) in a helium-neon (He-Ne) laser is around 5:1, meaning there is approximately five times more helium than neon in the laser tube. Helium serves as the primary energy source while neon provides the lasing action to produce the laser light.
