What is the stabilization energy of Be2 molecule?

Answer: Use molecular orbital theory to explain why the Be2 molecule does not exist. From the electronic configuration it is clear that there is no singly filled atomic orbital present in beryllium. Without the half filled orbital,the overlapping is not possible ,therefore Be2 molecule does not exist.

What is the bond order for Be2 -?

Answer and Explanation: The bond order for Be2 is 0 (zero). The valence shell of each beryllium atom is 2s2 so there are a total of four valence shell electrons for which we… See full answer below.

Why is H2 more stable than Be2?

H2 is more stable because it is diamagnectic, whereas Be2 is paramagnectica.

Why is Be2 unstable?

From the electronic configuration it is clear that there is no singly filled atomic orbital present in beryllium. Without the half- filled orbital, the overlapping is not possible, therefore Be2 molecule does not exist.

Is Be2 − paramagnetic or diamagnetic?

2s-2p mixing means combining the s and orbitals together with the same plane lying and associated with the same energy which leads to the energy change and the bond order respectively. And From the MOT concept Be2 doesn’t exists as its Border is 0 and in case of para or dia it is diamagnetic.

Why is Be2 not stable?

The electronic configuration of Beryllium is 1s2 2s2. From the electronic configuration it is clear that there is no singly filled atomic orbital present in beryllium. Without the half- filled orbital, the overlapping is not possible, therefore Be2 molecule does not exist.

Is Be2+ stable or unstable?

Here Be2+ ion is given hence, total number of electrons in Be2+ ion must be equal to 7. If an atom or molecule has certain bond order then it is said to be stable. Greater the bond order more will be the stability. Thus Be2+ ion is stable.

Is Be2 more stable than H2?

When comparing Be2 and H2: I. Be2 is more stable because it contains both bonding and antibonding valence electrons.

Which of the following bonding molecular orbital has higher energy?

The correct answer is Bonding molecular orbital has higher energy than antibonding molecular orbital. Explanation: Bonding molecular orbital has higher energy than antibonding molecular orbital. Electron from bonding molecular orbital of higher stability is lost (requires higher energy).

Why Be2 does not exist explain with molecular orbital diagram?

Is Be2 molecule paramagnetic or diamagnetic?

2py MO contains unpaired electron, therefore B2 molecule is paramagnetic.

Is Be2 paramagnetic in nature?

Since, B2 has two unpaired electrons, therefore, B2 is paramagnetic C2 has no unpaired electron, therefore, C2 is diamagnetic.

Is Be2 paramagnetic or diamagnetic?

Magnetic property: Since bond order is zero, Be2 molecule does not exist. It is diamagnetic due to the absence of any unpaired electron. B2 molecule is formed by the overlap of atomic orbitals of both boron atoms.

Which is more stable Be2+ and Be2?

Be2 is more stable than either Be2+ or Be2-.

Does Be2 exist in the gas phase?

Since both have a bond order of +12, both Be+2 and Be−2 will exist in gas phase.

How do you know which orbital has higher energy?

Within a given principal energy level, the energy of the electrons in the p orbital will be more energetic than the electrons in the s orbital. The energy of the electrons in the d orbital will be more than the p orbital. Similarly, the energy of the f orbital will be more than the d orbital.

Which of the following molecular orbital has the lowest energy of water molecule?

1 Answer. Explanation: Energy of bonding orbitals is less than antibonding orbital so σ2px has lowest energy than other given.

How many electrons are there in Be2?

Each of the two lithium atoms has one valence electron. Hence, we have two valence electrons available for the σ2s bonding molecular orbital….The Diatomic Molecules of the Second Period.

Molecule	Electron Configuration	Bond Order
Li2	(σ2s)2	1
Be2 (unstable)	(σ2s)2(σ∗2s)2	0
B2	(σ2s)2(σ∗2s)2(π2py,π2pz)2	1

What is the molecular orbital electronic configuration of Be2?

The molecular orbital electronic configuration,Magnetic property: Since bond order is zero, Be2 molecule does not exist. It is diamagnetic due to the absence of.1.

How many unoccupied molecular orbitals does H2O have?

Molecular Orbitals for Water (H 2 O) The five occupied and the lowest three unoccupied molecular orbitals of the isolated molecule (1 a 1) 2 (2 a 1) 2 (1 b 2) 2 (3 a 1) 2 (1 b 1) 2 were calculated using the Restricted Hartree-Fock wave function (RHF) using the G** basis set.

What is Be2 and B2 molecules?

Be2 molecule is formed by the overlap of atomic orbitals of both beryllium atoms. B2 molecule is formed by the overlap of atomic orbitals of both boron atoms.

What is the molecular orbital theory of hydrogen?

Molecular orbitals of Li 2, Be 2, to F 2 The molecular orbital theory (MO) has been introduced for the diatomic hydrogen molecules. The same method can be applied to for other diatomic molecules, but involving more than the 1 s atomic orbitals.
