In simplest terms, an ion occurs when an atom has a different number of electrons than expected. Ions can be either positively or negatively charged. (If # of electrons goes up, then the charge becomes more negative, if the # of electrons goes down, the charge becomes more positive.)
Therefore theoretically a helium atom would have to either gain electrons (for a total of 3 or more electrons), or lose electrons (for a total of 1 or 0 electrons).
Speaking about the helium atom specifically, you won't see ions of helium as commonly as you would see ions of other atoms due to the very high ionization energy required for the 1st electron and the essentially nonexistent electroegativity(Pauling scale).
There are antiprotonic helium ions (where an antiproton orbits a helium nucleus). Refer to studies conducted 2005-2006 by CERN on anitprotons and antiprotonic helium.
Helium is a neutral atom that has several isotopes and can become an ion.
Helium atom is neutral and has no charge. It becomes a positive ion with a charge of +1 when it loses an electron.
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+.
Yes, I think so
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.
It depends on the charge of the atom/ion however in a no-charged state Helium will have 2 electrons. If the Helium is charged negatively will have more. If it is charged possitively (up to 2+) it will have less. As Helium is a noble gas, it is rarely found in a charged state!
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.
The ions of elements nitrogen (N3-), oxygen (O2-), and fluorine (F-) will have the same electron configuration as a sodium ion (Na+), which is the same as the electron configuration of the noble gas neon.
When an alpha particle (helium nucleus) absorbs one electron, it becomes a helium atom. The resulting atom is neutral and has two protons, two neutrons, and two electrons.
the first inoization energy is 2372.3 kJ mol-1 there are 6.0221415 × 10^23 in a mole from avagadros number, devide the ionization energy for one mole by the number of atoms in a mole and you get the first ionization energy for one atom.
All noble gases can be ionised- helium is no exception- it is not easy- it can be done in plasmas, glow discharge tubes.
An electron is transferred from the 2s orbital of a lithium atom to create a Li+ ion.
