Is he2 stable
WebApr 10, 2024 · Hint: Molecular orbital theory states that atoms combine together to form molecular orbitals. The total number of molecular orbitals formed will be equal to the atomic orbitals forming molecular orbitals. We solve this sum by applying the relation between molecular orbital theory and bond order. WebNov 10, 2014 · This leads to a bond order of $\frac{1}{2}(2-1+1) = 1$, and therefore $\ce{He2^*}$ is stable with respect to $\ce{He + He^*}$. The excited dimer is known as an excimer . As an aside: The relative energy levels of the molecular orbitals are very hard to get right out of the blue, so take them with a grain of salt.
Is he2 stable
Did you know?
WebOut of H2+ and H2- which one is more stable and why though the B.O. is same Solution Because H2- contains one electron in the antibonding orbital which results in repulsion and decrease the stability . on the other hand H2+ does not contain any electron in the antibonding molecular orbital.

WebAlthough there are nine known isotopes of helium (2 He) (standard atomic weight: 4.002 602 (2)), only helium-3 (3 He) and helium-4 (4 He) are stable. All radioisotopes are short-lived, the longest-lived being 6 He with a half-life of 806.92(24) milliseconds.The least stable is 10 He, with a half-life of 260(40) yoctoseconds (2.6(4) × 10 −22 s), although it is … WebSep 5, 2024 · Which is more stable He2 or He2+? He2^+2 ion is more stable than He2 molecule. Why is H2 stable but not He2? H₂ is formed dew to s-s overlapp. Whereas atomic number of helium is 2 . It’s electronic configuration is 1s². Filled orbital can not overlapp and hence cannot form a bond.
WebHe2 doesn’t exist because helium is a noble gas. They are already stable, they don’t lose or gain electrons to become stable. So, He2 is not possible to exist. Was this answer …
