Why is H2 more stable than He2

Answered By: Patrick Coleman Date: created: Aug 02 2022

Is my reasoning on this correct: According to MO theory, H2 + will be more stable than He2 + because while they both have same bond order, He2 + has anti bonding electrons which destabilizes the molecule..

Asked By: Logan Bell Date: created: Sep 11 2021

Which is more stable He2 or He2+

Answered By: Sebastian Williams Date: created: Sep 11 2021

Molecular ion (He2)+ has a bond order of 0.5 , while (H2)+ has a bond order 0.5. … He2+ is the more stable of the pair because it has two electrons that it can release to form the ion.

Which has a longer bond B2 or B2+

Answered By: Ethan Washington Date: created: Sep 23 2021

Ans: B 2 + {\rm{B}}_2^ + B2+ has longer bond length.

Which Cannot exist on the basis of mot

Answered By: Jackson Taylor Date: created: Jun 14 2021

Hence, He2 cannot exist as it has zero bond order.

Asked By: Gabriel Butler Date: created: May 28 2021

Why He2 does not exist according to VBT

Answered By: Bryan Lopez Date: created: May 31 2021

Each helium atom has two electrons in 1s-orbital and therefore, there are four electrons in He2 molecule. … The zero bond order value indicates that there is no net bonding and He2 molecule should not be formed. In fact, there is no experimental evidence for the existence of this molecule.

Asked By: Cody Watson Date: created: May 19 2022

Why does He2 exist

Answered By: Edward Ward Date: created: May 19 2022

In He2 molecule attraction between nutron and electron of two atom is less than repulsion . That is why He2 is not exist. Because in MOT the bond order of He2 is 0 as there are two bonding and two anti-bonding pairs . According to the MOT if bond order is 0 or less than 0 then the molecule will not exist.

Asked By: Miles Martinez Date: created: Jan 02 2022

Is B2 a stable molecule

Answered By: Fred Peterson Date: created: Jan 05 2022

B2 is a known molecule in gas phase, although not very stable, whose existence has been predicted in terms of MOT because it has a Bond Order greater than zero (in the case of B2, the bond order is 1).

Asked By: Zachary Thompson Date: created: Apr 06 2021

Is He2 stable or unstable

Answered By: Jeremiah Taylor Date: created: Apr 09 2021

Therefore, He2 molecules are not predicted to be stable (and are not stable) in the lowest energy ground state. … Thus excited He2 molecules can form, but they spontaneously break apart as the electron(s) fall back to the ground state, where the bond order equals zero.

Asked By: Kevin Jenkins Date: created: Jan 05 2022

Is H2 stable or unstable

Answered By: Connor Flores Date: created: Jan 07 2022

Hydrogen only has one electron in its lowest energy level. This is a very unstable arrangement, and hydrogen gas undergoes a variety of reactions so as to reach a stable electron configuration where its energy level is either empty of electrons, or filled with electrons.

Asked By: Raymond Clark Date: created: Dec 31 2021

Does He2 2 exist

Answered By: Clifford Turner Date: created: Jan 02 2022

There is no bond existing between atoms of He2. So He2 does not exist.

Asked By: Raymond Hernandez Date: created: Jul 12 2021

Which is more stable B2 or Li2

Answered By: Kyle Phillips Date: created: Jul 14 2021

Why is B2 more stable than Li2? Both B2 and Li2 have bond order equal to 1. Thus, Li2 should have been more stable than B2 if we consider the number of electrons in the antibonding molecular orbital as the parameter of stability. …

Asked By: Robert Walker Date: created: Sep 19 2021

Why ne2 does not exist

Answered By: Malcolm Bryant Date: created: Sep 21 2021

Noble gases are non-reactive by nature. The outermost shell in Ne element is fully filled with electrons where the electron is 10 in number. This means that will have 20 electrons. This is why it does not need to react with any other atom and so has no bond order and cannot exist.

Asked By: Miles Green Date: created: Aug 29 2021

Does He2+ exist as a stable molecule

Answered By: Howard Hughes Date: created: Aug 31 2021

Therefore, He2 molecules are not predicted to be stable (and are not stable) in the lowest energy ground state. However, in a high-energy environment, electron(s) from the antibonding orbitals in He2 can be promoted into higher-energy bonding orbitals, thus giving a nonzero bond order and a “reason” to form.
