Helium is a noble gas and it is chemically stable.It does not have valence electrons to form bonds.
No, helium exists as He, with a single electron in its outer shell. The H2 molecule refers to two hydrogen atoms bonded together.
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.
He2 exists only in discharge tubes because it is an excited state of the helium atom that is created in the high-energy environment of discharge tubes. When electrical energy is passed through the tube, helium atoms are ionized and excited to create He2 molecules, which are unstable and quickly dissociate back into individual helium atoms.
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.
consists of two protons and two neutrons (ionized helium, He2+)
He2 does not exist. MO theory predicts a bond order of zero.
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, Helium is a noble gas and a mono-atomic elementary gas (He)

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.

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.
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.
The he2 molecular orbital diagram is important for understanding how helium dimer molecules bond and their electronic structure. It shows the arrangement of electrons in the molecule's orbitals, which helps explain how the two helium atoms interact and form a stable molecule. This diagram provides insights into the bonding and energy levels of the electrons in the helium dimer, shedding light on its overall stability and properties.
