diatomic gas molecules

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 ..

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..

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 molecule (He 2..

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..

The molecules of a gas are far apart. The inter-molecular force of attraction is negligible and they have no fixed freedom of motion. Hence gases have neither fixed shape nor volume. They completely occupy the container and take the shape and the volume of the container. Mo..

Avagadro's law helps us to determine the molecular formula of gases like ammonia, carbon dioxide, sulphur dioxide etc. Exampl..

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. Homoatomic ..

Carbon atom has four electrons in its outermost shell. Thus, it requires four more electrons to acquire a stable noble gas configuration. Each of the hydrogen atoms has only one electron in its outermost shell and requires one more electron to complete its outermost shell (to acquire He..

An oxygen atom has six electrons in its valence shell. As a result, it requires 2 more electrons to achieve the nearest noble gas configuration. When two oxygen atoms share two pairs of electrons this is achieved: ..

Hydrogen atom has only one electron in its outermost shell, and requires one more electron 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 format..
