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.
When a helium atom loses an electron, it forms a helium ion which is positively charged because it has one less electron than protons. This helium ion is written as He+.
Both the hydride ion (H-) and helium atom have two electrons. The hydride ion gains an extra electron to achieve an electron configuration similar to helium (1s²), making them both have two electrons overall. Helium naturally has two electrons in its electron configuration.
Helium atom is neutral and has no charge. It becomes a positive ion with a charge of +1 when it loses an electron.
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.
Helium has two valence electrons. O6+ ion (a hypothetical ion) will also have 2 valence electrons.

Helium is chemically inert and does not form any type of ions.
The formula of the hydride formed by helium is HeH+. It's a cationic species known as the helium hydride ion, which is formed when helium reacts with hydrogen ions in very low-temperature environments such as interstellar space.

A positive ion is formed when atoms lose electrons. When a cell gains an electron it becomes negative

Helium will not react with carbon as helium is chemically inert.
Helium atom is neutral and has no charge. It becomes a positive ion with a charge of +1 when it loses an electron.
Helium is a neutral atom that has several isotopes and can become an ion.
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.
Negatively charged anions are formed.
Helium has two valence electrons. O6+ ion (a hypothetical ion) will also have 2 valence electrons.
