How do the LCAO model explain the fact that He have a bond energy og 1e-3 and average bond length of 50 angstrom?

He does not form a chemical compound. The He2 molecule is not knon. The He2+ cation has a very transient existence and has a reportedly very short bond length of approximately 0.75 Angstrom.


Is He2 joined by a double covalent bond?

He2 does NOT exist, Helium is a noble gas and a mono-atomic elementary gas (He)


What diatomic molecules is joined by a double covalent bond O2 cl2 n2 he2?

O2 and N2 are diatomic molecules that are joined by a double covalent bond. Cl2 and He2 do not exist as stable diatomic molecules with double covalent bonds.


What diatomic molecules are joining by a double covalent bond o2 cl2 n2 he2?

He2 does not exist.Cl2 is joined by a single covalent bond and N2 by a triple covalent bond.That means O2 is the molecule joined by double covalent bond


Why can't He2 exist?

Helium exists in the form of He and not He2 because He has already stable,does not take part in a chemical reaction.But when one atom combines with other atom in a chemical reaction to form bond to complete its outermost shell and attain stabilty while He does not combine with other atom to form bond.This is the reason for helium does not exist in the form He2 or molecule form


What is the significance of the He2 MO diagram in understanding the bonding and electronic structure of helium dimer?

The He2 molecular orbital (MO) diagram is important for understanding how the two helium atoms in a helium dimer bond together. It shows the energy levels and arrangement of electrons in the molecule, which helps explain the bonding and electronic structure of the helium dimer.

What is The number of blank pairs in a covalent bond equals the bond order?

The bond order is the number of shared electron pairs between two atoms in a covalent bond. A single bond has a bond order of 1 (one shared pair), a double bond has a bond order of 2 (two shared pairs), and a triple bond has a bond order of 3 (three shared pairs).
