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.
no
Helium is an element. It is a chemical element with the symbol He and atomic number 2. Helium exists as individual helium atoms, not molecules.
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.
Helium is a noble gas and it is chemically stable.It does not have valence electrons to form bonds.
He2 does NOT exist, Helium is a noble gas and a mono-atomic elementary gas (He)
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

He2 does not exist. MO theory predicts a bond order of zero.
no
Alpha rays are helium ions, He2+.

The Chinese character 和(he2) means "and."
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
i dont know. dont ask me
