Why he2 does not exist .explain in terms of lcaos?
Helium is a noble gas and it is chemically stable.It does not have valence electrons to form bonds.
Why he2 exists only in discharge tubes?
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.
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.
An alpha particle is a form of ionizing radiation which consists of?
consists of two protons and two neutrons (ionized helium, He2+)
What is the bond order for He2?
He2 does not exist. MO theory predicts a bond order of zero.
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
Is He2 joined by a double covalent bond?
He2 does NOT exist, Helium is a noble gas and a mono-atomic elementary gas (He)

What is the significance of the He2 MO diagram in understanding the bonding and electronic structure of helium dimer?
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.
Is helium a element or molicles?

Does alpha rays contains only a positive charge of atom?
Alpha rays are helium ions, He2+.

Why helium exist in the form of he not he2?
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.
What is the significance of the he2 molecular orbital diagram in understanding the bonding and electronic structure of helium dimer molecules?
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.
