Yes helium is an atom. It is stable. It is placed in group 18.
Yes, helium is a monoatomic molecule. It is stable itself as it has already achieved maximum possible electrons in its outermost shell. It is the only element in group 18 without 8 electrons in valence shell.

Yes, helium is an element that has 2 protons, 2 neutrons, and 2 electrons. It iis part of the noble gases.
No, helium is an element. It is in group 18 on the periodic table, which is the noble gas family. Noble gases do not normally undergo chemical reactions so they don't form ions.
Helium is an element. it is a gas which is monoatomic that is to say it does not form molecules but is present as atoms.

Yes.
The Hydride ion (H-) and the lithium ion (Li+).

Lithium is formed through the fusion of a hydrogen and a helium ion. This will only occur at very high temperatures and pressures.
The chemical symbol for helium is "He."
The beryllium ion Be2+ has the electronic configuration 1s2, a full valence shell, the same as helium, an inert gas. Neon is an inert gas, with an electronic configuration of 1s2 2s2 2p6.Be2+ and Ne therefore both have inert gas configurations and have full valence shells.
Helium is typically monatomic, even as an ion.
Helium does not form ion.
Helium is a neutral atom that has several isotopes and can become an 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.
The Hydride ion (H-) and the lithium ion (Li+).
Nuclear emission of a helium ion is called alpha decay.
Helium is chemically inert and does not form any type of ions.
Type your answer here... when helium atom removes a electron it forms a helium+ ion.(He+)
Helium has 2 electrons. hydrogen has one electron. Hydride ion is formed when hydrogen gains one electron, and thus hydride ion will also have 2 electrons.
The unstable ion (NeHe)+ is known.
