Helium is an inert gas meaning that it will not combine with other elements or compounds. More specifically, chlorine will not bond with helium.
But, if it did, as could happen in a supernova explosion, since chlorine is 17 on the periodic chart, and helium is 2, when they fuse they would create an atom of potassium which is 19.
Helium has the highest ionization energy of all the elements because it has a full outer electron shell, making it very stable and reluctant to lose an electron.
Helium and neon would not be capable of forming an ionic bond because they are noble gases and already have a full valence shell of electrons, making them stable and unlikely to gain or lose electrons.
A charged chlorine atom, or a chlorine ion, would have gained or lost an electron. If it gained an electron, it would have a charge of -1. If it lost an electron, it would have a charge of +1.
Chlorine typically has a charge of -1 as an ion.

Helium ash is merely helium. Helium is commonly referred to as ash in discussions of our sun's fuel (and others stars of similar size/composition) to indicate that it cannot burn (or really cannot be fused into a larger atomic element). Our sun fuses hydrogen into helium at its core but the temperatures and pressures are not high enough to fuse helium, so it is called ash. If the core had a higher temperature/pressure, the helium would be fused into a larger element (carbon), something that happens with more massive stars. In such a star it would not be called ash because the conditions would be such that it could be fused ("burned"), so it would merely be called helium.
Helium and neon would not be capable of forming an ionic bond because they are noble gases and already have a full valence shell of electrons, making them stable and unlikely to gain or lose electrons.
A white dwarf is the remnant of a star that has fused all the hydrogen and helium in its core, leaving mostly carbon and oxygen nuclei.
Sodium would like to react with chlorine, as it would form the stable compound sodium chloride (table salt). Sodium typically reacts with nonmetals like chlorine to achieve a stable electron configuration. Helium and argon are noble gases and are already stable, so sodium wouldn't typically react with them. Iron is a transition metal and is less likely to react with sodium to form a stable compound.
That would be the hydrogen in the sun. The second most plentiful substancein the solar system would be the helium in the sun, being the fused hydrogen.
No, it rarely bonds with other elements, and if it does the only one it would bond with would be Fluorine, which they have done before, and if and when it bonds with fluorine and/or oxygen, it would form a covalent bond. If you were to to take either of the two elements and try to perform an chemical reaction, when you find the electro negativity (ΔEn, which is equal to En2-En1) you will notice that it will fall below 0.5 or greater than 1.7 , which will be a covalent bond (an ionic bond will be between 0.5 and 1.7).
An environment of helium could be fatal if it excluded oxygen to the degree that humans would be suffocated. Those squeaky voices in cartoons are often created by people breathing helium before speaking. However, they don't breathe helium for extended periods.
Any of the Halogens (Fluorine, Chlorine, Bromine, Iodine, and Astatine) or Noble Gases (Helium, Neon, Argon, Krypton, Xenon, Radon) would be considered a nonmetal.
