What is the electron configuration of the He2+ ion?
What is the electron configuration of the He2+ ion?
The ground state MO electron configuration for He2 is (σ1s)2(σ1s*)2 giving a bond order of 0. ground state. (He-3)2 molecules are indeed not stable, and neither are He-3-He-4 molecules. But (He-4)2 molecules ARE stable.
What is the bond order of he22+?
The bond order for He2+ is: The answer is b. 1/2.
What is the bond order of He2+ according to molecular orbital?
Bond order of is 0.5.
How many electrons does He2+ have?
The He2+ molecule has three valence electrons. The He2 molecule has four valence electrons. In the Lewis Structure Theory we had single, double, and triple bonds, in the Molecular Orbital Theory we similarly define the bond order.
Does He2 2+ exist?
Based on molecular orbital theory, He2 should not exist, and a chemical bond cannot form between the atoms. However, the van der Waals force exists between helium atoms as shown by the existence of liquid helium, and at a certain range of distances between atoms the attraction exceeds the repulsion.
What is the energy level of an electron?
What Are Energy Levels? Energy levels (also called electron shells) are fixed distances from the nucleus of an atom where electrons may be found. Electrons are tiny, negatively charged particles in an atom that move around the positive nucleus at the center. Energy levels are a little like the steps of a staircase.
Why is He2+ unstable?
Just to add a final point, He2 is unstable because it has two electrons in the BMO and two in the AMO, so BO=(2–2)=0. First, look at the atoms. H and He have only an s orbital, He has that s orbital filled (since each orbital takes two electrons), and so there is no need for another atom to bond to.
Is He2+ paramagnetic or diamagnetic?
Let it be H2- ,H2+ or He2+ ; there’s an unpaired electron i.e, they are paramagnetic.
What is the bond order of the He2+ ion would you expect this ion to be stable relative to the separated He atom and ion?
What is the bond order of the He2+ ion? Would you expect this ion to be stable relative to the separated He atom and He+ ion? Because the bond order is greater than 0, the He2+ molecular ion is predicted to be stable relative to the separated He and He+.
Why is He2+ more stable than He2?
H2+ will be more stable than He2+ because while they both have same bond order, He2+ has anti bonding electrons which destabilizes the molecule.
