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.

Nuclear emission of a helium ion is called alpha decay.
Helium is chemically inert and does not form any type of ions.
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+.
When helium loses an electron, it becomes a positively charged helium ion (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.
Lithium ion (Li+) and beryllium ion (Be2+) have the same electron configuration as helium because they both have filled electron shells.
Helium is typically monatomic, even as an ion.
