Which is more stable Li2 or Li2?

Li2+ is more stable than Li2− because Li2− has more numbers of antibonding electrons.

Which is more stable Li+ or Li?

Also Li atom is more stable than Li+. However, in aqueous medium, due to extremely large hydration energy (energy evolved when a substance is hydrolysed), in aqueous medium, Li+ is more stable.

Which one is more stable according to MOT?

O2+ is more stable than O2-. Because According to molecular orbital theory O2+ has 15 electrons ⁢ has one electron in antibonding orbital. In the case of O2- 17 electrons are present &3 electrons are present in antibonding orbitals.

Which has a stronger bond Li2 or Li2+?

Li2 , Li2 + , Li2 – Since the bond order of Li2 is higher than Li2 + and Li2 – . Therefore ,Li2 has stronger single covalent bonding . Thus lithium molecule (Li2) is more stable.

Does Li2 exist according to MOT?

Li molecule exists whereas Be molecule does not exist . The existence of a molecule can be predicted by knowledge of molecular orbital theory ( MOT ) . The molecule having bond order more than zero may exist .

Why is Li 1 more stable than Li?

Compare the stability of a lithium atom with that of its ion, Li. The Li+ ion is more stable because it has a complete octet. The two causes are the attraction between the positive nucleus of one atom and the negative electrons of another atom, and the attraction between positive ions and negative ions.

Is lithium molecule stable?

‘stone’) is a chemical element with the symbol Li and atomic number 3. It is a soft, silvery-white alkali metal. The nucleus of the lithium atom verges on instability, since the two stable lithium isotopes found in nature have among the lowest binding energies per nucleon of all stable nuclides.

Is Li2 − Li2 − paramagnetic or diamagnetic?

Li2 only has 2 electrons. If you draw the MO diagram, they should both be in the sigma 2s bonding orbital. They are both paired, so it is diamagnetic.

Which molecule or ion has the highest bond order?

O2
O2 has the highest bond order.

Is Li2 stable or unstable?

Li2 is more stable than Li+2 , because the bond is (hypothetically) stronger (probably gas-phase). for each electron in a bonding MO, it adds 0.5 to the bond order, because more bonding character strengthens the bond…
