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.

∙ 11y agoNo, 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.

What is isoelectronic with helium?
The Hydride ion (H-) and the lithium ion (Li+).
Element similar to helium and neon?
helium argon krypton xenon radon
How is lithium formed in stars?
Lithium is formed through the fusion of a hydrogen and a helium ion. This will only occur at very high temperatures and pressures.
What are the symbols for hydrogen and helium?
The chemical symbol for helium is "He."
What do a beryllium ion and neon atom have in common?
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.
Is helium a polyatomic ion?
Helium is typically monatomic, even as an ion.
What is the ion charge of a helium atom Is it plus 1?
Helium does not form ion.
Is helium an isotope atom or ion?
Helium is a neutral atom that has several isotopes and can become an ion.
Why is o6 a helium like ion?
Helium has two valence electrons. O6+ ion (a hypothetical ion) will also have 2 valence electrons.
Is the helium ion positive or negative?
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.
What is isoelectronic with helium?
The Hydride ion (H-) and the lithium ion (Li+).
If a helium ion is emmited during the disintegration of a nucleus what kind of decay is this called?
Nuclear emission of a helium ion is called alpha decay.
What is helium's type of ion?
Helium is chemically inert and does not form any type of ions.
When a helium atom loses an electron then what is formed?
Type your answer here... when helium atom removes a electron it forms a helium+ ion.(He+)
How hydride ion and helium atom have same number of electron?
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.
What can helium and neon combine with?
The unstable ion (NeHe)+ is known.
What is the series limit for paschen series of helium ion?
2052 Angstrom.
