Hint: Helium is a colorless, odorless, tasteless, non-toxic, inert monatomic gas that belongs to the noble gas section of the periodic table. It has the lowest boiling point of all the elements. In the observable universe, helium is the second lightest and most abundant element.
Complete answer:
There are only two valence electrons in the ion (two from each He atom minus two for the charge). The molecular orbital diagram can now be filled in.
The two electrons occupy the bonding orbital, which is the lowest energy molecular orbital, resulting in an electron configuration. So, the bond order is
As a result, is expected to contain a single bond. As a result, it should be a stable species.
Let us take a look at the molecules, which are made up of two atoms with the electronic configuration.
Both the bonding and antibonding orbitals must contain two electrons with a total of four valence electrons. This results in an electronic configuration of .
So, the bond order is
Bond order
The molecule has no net covalent bond, indicating that it is not a stable species.
Note:
Cryogenics (the largest single use, accounting for about a quarter of production) uses liquid helium to cool superconducting magnets, with MRI scanners being the most popular commercial use.
Inhaling a small amount of helium temporarily alters the timbre and quality of the human voice, just as it does for any gas whose density varies from that of air.
