The number of electrons in an atom's outer electron shell determines how many dots there are. Helium has 2 electrons in its outer electron shell, so 2 dots.
The symbol for the noble gas Argon (atomic number = 18) is Ar.

Neon atoms have 8 valence electrons. Refer to the related link for an illustration of the electron dot diagram for neon.
.. H : Cl : .. put a full valence shell around chlorine (Cl) and put Hydrogen (H) to the left next to a pair of electrons.
Eight, except for helium, which has a maximum of two.

The electrons in the outermost shell of an atom is known as the valence electrons. These valence electrons determine the reactivity of the atom.
Helium has only 2 electrons in its outer electron shell, so 2 dots.
