In stable equilibrium position, the two atoms in a diatomic molecule are separated by a certain distance r 0 . This distance is called intermolecular distance or bond lengt..

In stable equilibrium position, the two atoms in a diatomic molecule are separated by a certain distance r 0 . This distance is called intermolecular distance or bond length. Let us imagine the diatomic molecule as a system of two tiny spheres at either end o..

Each helium atom has two electrons in 1s-orbital and therefore, there are four electrons in He 2 molecule. These electrons will be accommodated in s i 1 ls and s *1s MOs as shown below. ..

Hypothetical Helium Molecule (He 2 ) - Each helium atom has two electrons in 1s-orbital and therefore, there are four electrons in He 2 molecule. These electrons will be accommodated in s i 1 ls and s *1s MOs as shown below. fig 1.18 - Molecular orbital energ..

Helium Molecule Ion (He 2 + ) - This molecule contains three electrons, two from one helium atom and one from the other helium (He + ) ion. The molecular orbital electronic configuration of the molecule is: Its bond dissociation energy has..

Atoms and Molecules - The smallest particle of an element, which may or may not have independent existence is called an atom, while the smallest particle of a substance which is capable of independent existence is called a molecule. Molecules are classified as homoatom..

The smallest particle of an element, which may or may not have independent existence is called an atom, while the smallest particle of a substance which is capable of independent existence is called a molecule. Molecules are classified as homoatomic and heteroatomic. Homoa..

Hydrogen atom has only one electron in its outermost shell, and requires one more to acquire the nearest noble gas configuration of helium (He: 1s 2 ). To do so, two hydrogen atoms contribute one electron each to share one pair of electrons between them. This leads to the formation of a ..
