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.
What else can I help you with?
What is an example of an atom that only exists in its molecular form?
An example of an atom that only exists in its molecular form would be oxygen. It is most commonly found as an O2 molecule.
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.
Does helium exist as he2?
No, helium exists as He, with a single electron in its outer shell. The H2 molecule refers to two hydrogen atoms bonded together.
Is helium a element or molicles?
helium is an element, it is a mono atomic molecule, He2 .
What is helium plus helium?
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.

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.
Is He2 joined by a double covalent bond?
He2 does NOT exist, Helium is a noble gas and a mono-atomic elementary gas (He)
Does helium exist as he2?
No, helium exists as He, with a single electron in its outer shell. The H2 molecule refers to two hydrogen atoms bonded together.
Does alpha rays contains only a positive charge of atom?
Alpha rays are helium ions, He2+.
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
What is the bond order for He2?
He2 does not exist. MO theory predicts a bond order of zero.
Is helium a element or molicles?
helium is an element, it is a mono atomic molecule, He2 .
He2 ping2 mean in Chinese?
peace
What does he mean in Chinese?
The Chinese character 和（he2) means "and."
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 is helium plus helium?
