## What is the molecular orbital electron configuration of He2 that is molecule of helium ion?

In this helium molecule, the combining orbitals are $1{s^2}$ and $1{s^2}$. These atomic orbitals are very close to the helium nucleus. Now, $(\sigma_{1s})^2$ atomic orbitals of two helium atoms form two molecular orbitals designated as $\sigma _{1s}$ and ${\sigma ^ * }_{1s}$.

## What is the electron configuration of He2?

The ground state MO electron configuration for He2 is (σ1s)2(σ1s*)2 giving a bond order of 0. the bond order equals zero.

## 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 bond order of He2 +?

1/2
The bond order of He2+ is 1/2. He2+ has 3 electrons. Hence, Bond order = (2-1)/2 = 1/2 = 0.5.

## Why He2 does not exist but He2 does?

The number of electrons in is 4. When bond order is 0, such a molecule does not exist. The bond order is not equal to 0, hence this molecule exists. Therefore, exists while does not exist.

## Why do He2 molecule not exist?

Answer: According to MOT;The bond order and stabilization energy of he2 molecule are zero. He2 molecule contains 4 electrons. This indicates that there is no bond formation between 2 HE atoms and hence the He2 molecule does not exist.

## How many electrons are in the bonding molecular orbital of He2+?

two electrons
Answer and Explanation: In the molecular di-cation of helium ion, two electrons are less than helium atom. Two electrons are to be filled in the molecular orbitals. These two electrons occupy bonding molecular orbital while antibonding molecular orbital remain vacant.

## How do you find the bond order of He2+?

The bond order of He2+ is 1/2. He2+ has 3 electrons. Hence, Bond order = (2-1)/2 = 1/2 = 0.5.

## How does He2 exist?

Based on molecular orbital theory, He2 should not exist, and a chemical bond cannot form between the atoms. So a molecule composed of two helium atoms bound by the van der Waals force can exist.

## How does the molecular orbital of He2 work?

A molecular orbital explicitly describes the spatial distribution of a single Energy Level Diagrams He2 has bond order 0 [ (2 − 2)/2 = 0], and we can make H+. According to the molecular orbital theory, in a supposed He2 molecule, both the if we draw its MOT DIAGRAM, 2 e’s enter the Bonding molecular Orbital and 2 .

## What is the molecular weight of iodine monochloride?

Iodine monochloride PubChem CID 24640 Synonyms IODINE MONOCHLORIDE 7790-99-0 Iodine chl Molecular Weight 162.36 Date s Modify 2021-08-28 Create 2005-03-27

## Why does H2 exist but not He2 +?

After a preliminary check with He2 and He2+, self‐consistent field calculations have been carried out for the nitrogen and carbon monoxide. This molecular orbital treatment can explain why H2 exists but He2 does not.

## Which is the best description of a molecular orbital diagram?

H−.A molecular orbital diagram, or MO diagram, is a qualitative descriptive tool explaining chemical bonding in molecules in terms of molecular orbital theory in general and the linear combination of atomic orbitals (LCAO) molecular orbital method in particular.
