Does helium exist as he2?
no
How do the LCAO model explain the fact that He have a bond energy og 1e-3 and average bond length of 50 angstrom?
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.
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.
An alpha particle is a form of ionizing radiation which consists of?
consists of two protons and two neutrons (ionized helium, He2+)
What type of decay is involved when polonium -214 decays into lead -210?
It is alpha decay. In the process, an alpha particle(He2+) is released. So, it is called alpha decay.
Does helium exist as he2?
no
What is the bond order for He2?
He2 does not exist. MO theory predicts a bond order of zero.
Is He2 joined by a double covalent bond?
He2 does NOT exist, Helium is a noble gas and a mono-atomic elementary gas (He)
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

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
Where you ca find Kenmore He2 plus schematic diagram?
i dont know. dont ask me
Does alpha rays contains only a positive charge of atom?
Alpha rays are helium ions, He2+.
Where can you find an online manual for the Kenmore HE2?
