It's a noble gas with a full outer shell of valence electron. It is naturally averse to losing any of them.
Noble gases' atoms have the least tendency to form ions.
Helium does not form ion.
Yes, helium can be induced to ionize (form ions) by applying a voltage across the gas in a plasma discharge tube, e.g. a "neon" sign. But under ordinary chemical conditions, helium does not ionize or form bonds (share its electrons) with other atoms.
You didn't provide an ion. So since it's a positive most likely a negative ion.
Helium has two valence electrons. O6+ ion (a hypothetical ion) will also have 2 valence electrons.

carbon
Helium is chemically inert and does not form any type of ions.

Helium is typically monatomic, even as an ion.
an ion and a sugar
Sulfur will form S2- ion
Helium is a neutral atom that has several isotopes and can become an ion.
You didn't provide an ion. So since it's a positive most likely a negative ion.
Helium has two valence electrons. O6+ ion (a hypothetical ion) will also have 2 valence electrons.
If one electron has been removed from Helium's electron shell then it is a He+ ion. If both of its electrons have been removed it becomes a He2+ ion. Either way they are both positive ions.
