The helium dimer is a van der Waals molecule with formula He2 consisting of two helium atoms. This chemical is the largest diatomic molecule—a molecule consisting of two atoms bonded together. The bond that holds this dimer together is so weak that it will break if the molecule rotates, or vibrates too … See more Based on molecular orbital theory, He2 should not exist, and a chemical bond cannot form between the atoms. However, the van der Waals force exists between helium atoms as shown by the existence of See more The helium dimer can be formed in small amounts when helium gas expands and cools as it passes through a nozzle in a gas beam. Only the isotope He can form molecules like this; … See more In a normal helium atom two electrons are found in the 1s orbital. However, if sufficient energy is added, one electron can be elevated to a higher energy level. This high energy electron can become a valence electron, and the electron that remains in the 1s … See more The dihelium excimer is an important component in the helium discharge lamp. A second use of dihelium ion is in ambient ionization techniques using low temperature … See more He2 is a related ion bonded by a half covalent bond. It can be formed in a helium electrical discharge. It recombines with electrons to form an electronically excited He2(a Σ u) excimer molecule. Both of these molecules are much smaller with more normally … See more In very strong magnetic fields, (around 750,000 Tesla) and low enough temperatures, helium atoms attract, and can even form linear chains. This may happen in white … See more He2 has been shown to form van der Waals compounds with other atoms forming bigger clusters such as MgHe2 and CaHe2. The helium-4 trimer ( He3), a cluster of three helium atoms, is predicted to have an excited state … See more Web2024 JC2 H2 Chemistry Prelim Temasek Junior College - Read online for free.

An unbound p-orbital electron in one atom forms an electron pair with a neighboring atom's unbound, parallel p-orbital electron. This electron pair forms the pi bond. Double and triple bonds between atoms are usually …

WebIn quantum mechanics, a Slater determinant is an expression that describes the wave function of a multi-fermionic system. It satisfies anti-symmetry requirements, and consequently the Pauli principle, by changing sign upon exchange of two electrons (or other fermions).
