Helium has two valence electrons. O6+ ion (a hypothetical ion) will also have 2 valence electrons.
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.
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+.
Argon Flourohydride and HydroHelium ion (+1) (HArF and HHe+ respectively).
When helium loses an electron, it becomes a positively charged helium ion (He+).
Helium is a neutral atom that has several isotopes and can become an ion.

Argon Flourohydride and HydroHelium ion (+1) (HArF and HHe+ respectively).
Nuclear emission of a helium ion is called alpha decay.
Helium is chemically inert and does not form any type of ions.
When helium loses an electron, it becomes a positively charged helium ion (He+).
Atoms or ions that have the same number of electrons as helium (2 electrons) are considered isoelectronic with helium. Examples of species that are isoelectronic with helium include H+, Li+, Be2+, and B3+.
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.
Lithium ion (Li+) and beryllium ion (Be2+) have the same electron configuration as helium because they both have filled electron shells.
The unstable ion (NeHe)+ is known.
