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


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

O2 is a double covalent bond (O=O) Cl2 is a single covalent bond (Cl-Cl( N2 is a triple covalent bond (N///N) He does NOT form any bonds, but remains MONATOMIC.


What is the bond order for He2?

He2 does not exist. MO theory predicts a bond order of zero.


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.


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

Is HE2 a van der waals?

He2 is a molecule where the bonding is only due to van der waals interactions as the molecular orbital diagram shows that both the bonding and antibonding sigma orbitals are full.


Why doesn't the He2 molecule form?

Atoms bond to get a full outer shell of electrons. For example, a hydrogen atom needs to gain 1 electron to achieve a full outer shell of 2. So it will bond with another hydrogen atoms and a pair of electrons is shared between them. Helium, however already has a full outer shell and so is most stable without bonds.
