How many valence neutrons does helium have?
First of all there is no such thing a a valence neutron. However there are valence electrons.Valence electrons are the electrons of the outer most layer or shell called valence shell. Based on a Bohr diagram or Lewis structure you can see that Helium has 2 valence electrons.

What element has a stable 2 valence electrons?
The element with a stable 2 valence electrons is helium. Helium has a full outer electron shell with 2 electrons, making it very stable and unreactive.
