Why is H2+ more stable?
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.
Is He2 or He2+ more stable?
Two electrons are to be filled in the molecular orbitals. These two electrons occupy bonding molecular orbital while antibonding molecular orbital remain vacant. The more is the bond order, the greater is the stability. So, He2+2 H e 2 2 + is more stable than He+2 H e 2 + .
Which out of H2+ and H2 is more stable and why?
In H2- ion one electron is present in anti bonding orbital due to which destabilizing effect is more and thus the stability is less than that of H2+ ion.
Why is H2+ less stable than H2?
H2 is simply a bond between 2 hydrogen atoms so energy is released . Whereas H2+ means you have to push out one electron from h2 so you need to provide energy . So as energy is inversely proportional to stability so h2 is more stable .
Is He2+ a stable molecule?
He2+ is the more stable of the pair because it has two electrons that it can release to form the ion. The same is not true of the H2+ ion.
Is the molecule H2+ stable?
Bond order The antibonding orbital is empty. Thus, H2 is a stable molecule.
Is He2 and He2 2+ more stable?
He2^+2 ion is more stable than He2 molecule.
Why H3 molecule is much less stable than the H2 molecule?
Although H2 and H3 both have two electrons in the lowest energy level, H3 also has an extra electron at the higher energy level (Eb), which tends to increase the net energy of the atom. Thus, the H3 molecule is much less stable than the H2 molecule.
Why is He2 not expected to be stable?
These electrons are present in the 1s orbital. The capacity of an s orbital is 2 electrons, i.e., helium is fully filled with required number of electrons. That means, it cannot take any more electrons or if it gives away one or both of its electrons it loses its stability.
