diatomic molecules are

A diatomic molecule has two atoms bonded to each other by a covalent bond. In such a molecule, the dipole moment of the bond gives the dipole moment of the molecule. Thus, a diatomic molecule is polar if the bond formed between the atoms ..

Bonding in Some Diatomic Molecules - Bonding in some homonuclear diatomic molecules of the elements of first and second rows of the periodic table: 1. Hydrogen molecule (H 2 ) 2. Hydrogen molecule ion (H 2 + ) 3. Hypothetical helium m..

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..

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..

A chlorine atom is extremely reactive. It cannot exist freely as it does not have a stable electronic configuration. Chlorine does not exist as single atom but as a diatomic molecule. A single covalent bond is formed between two chlorine atoms. Each chlorine atom has an ele..

Dihydrogen - Hydrogen is the first element in the periodic table and is the lightest known element. It was discovered by Henry Cavendish in 1766. It exists as a diatomic molecule H 2 . Its name hydrogen was proposed because it produces water on burning with oxygen (in Greek; hyd..

In 1772 Daniel Rutherford discovered Nitrogen. Nitrogen is the first member of group 15 of the periodic table. Nitrogen exists as a diatomic molecule (N 2 ) with a triple bond between the nitrogen atoms (NN). So nitrogen gas is also called dinitrogen. Its electronic configuratio..

The combining atomic orbitals should not differ much in energies. For e.g., in case of homonuclear diatomic molecules of the type A 2 ' 2s-orbital of one atom can combine with 2s-orbital of another atom but 1s-orbital of one atom cannot combine with 2s-orbital of another a..
