He2 does NOT exist, Helium is a noble gas and a mono-atomic elementary gas (He)
He, helium, exists as a monoatomic gas, not a diatomic gas.
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
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.
He2 does not exist. MO theory predicts a bond order of zero.
Because of a death causing gaseous fume that contains B5 He2 Be3
The element helium (He) is an inert or noble gas. It, like the other inert gases, is not interested in any kind of electron borrowing, loaning or sharing arrangements. It will tend not to gain or lose electrons.

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 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
no
peace
The Chinese character 和(he2) means "and."
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.
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.
i dont know. dont ask me
Alpha rays are helium ions, He2+.
