Is helium a polyatomic ion?
Helium is typically monatomic, even as an ion.
What element that forms an ion has the highest electronegativity?
If only the monopositive ions are considered, helium would create the ion with highest electronegativity.
What atom contains 1 electron and 2 protons?
None, for it to be an atom it has the have the same number of electrons and protons. Something with 1 electron and 2 protons would theoretically be a helium ion but helium does not form ions.
What is the electron configuration of the neutral lithium atom?
.. [Li]+ [:I:]- (put the last 2 pairs above and below the "I" this wont let me) ..
What is meant by ionization limit?
Ionization is the physical process of converting an atom or molecule into an ion by adding or removing charged particles such as electrons or other ions. And the highest point to which we can ionize an element is called its ionization limit.
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+)
Is there a limit to the negative charge that can occur on an ion?
Yes, there is a limit to negative charge that can occur on an ion.
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.
