Helium is a noble gas and it is chemically stable.It does not have valence electrons to form bonds.
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.
helium is an element, it is a mono atomic molecule, He2 .
When two helium atoms combine, they form a molecule of helium gas (He2), which is also known as a dihelium molecule. This molecule is quite rare and unstable under normal conditions, as helium typically exists as a monoatomic gas.
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.

he2 is a fatty. He atom is a inert gas. so it can not react with any other atom or molecules to form any compounds.so He2 can't exist. ANOTHER ANSWER: Helium atom has only one shell i-e K-shell which can accommodate a maximum of two electrons which it already has. therefore Helium atom does not need any more electrons to become stable as it is already stable by duplet rule. Thus helium atom does not combine with another helium atom and hence exists as He and not He2.
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.
