Here's why:

* Neon is a noble gas: Neon is in group 18 of the periodic table, also known as the noble gases. These elements have a full outer shell of electrons, making them extremely stable and unreactive.

* Hydrochloric acid is an acid: It is a strong acid that readily donates protons (H+ ions).

* No chemical reaction: The stable electronic configuration of neon prevents it from readily forming bonds with other elements, including hydrogen or chlorine.

Therefore, neon and hydrochloric acid will not interact to form any new chemical compounds.
