double bond molecule

F ormation of oxygen (O 2 ) molecule Each oxygen atom has six electrons in its valence shell. Thus, it requires 2 more electrons to achieve the nearest noble gas configuration. This is achieved by sharing two pairs of electrons by the two oxygen atoms as shown below: ..

Double Covalent Bond - A double covalent bond consists of two pairs of shared electrons. It is formed by the sharing of two pairs of electrons between two atoms. It is actually a combination of two single bonds. It is represented by putting two shor..

Shapes of Molecules - such as linear, triangular, square planar, pyramidal, octahedral etc. The shape of a molecule affects its chemical and physical properties. For instance, some of the unique properties of water are due to the angular shape of its molecule (H 2 O). ..

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 a molecule having three bond pairs of electrons around its central atom, the electron pairs form an equilateral triangular arrangement around the central atom. These molecules have trigonal planar (or triangularplanar) shape and the three bond pairs are a..

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 ) 4. Helium molecule ion (He..

Molecule having four bond pairs of electrons around the central atom, arrange their electrons tetrahedrally. These molecules have tetrahedral shapes and the four bond pairs are at an angle of 10928' with respect to each other. Some molecules which ..

Hydrogen molecule - The bonding between hydrogen atoms to form a molecule of hydrogen can be represented as follows: In this representation, half-filled '1s' orbital of one hydrogen atom overlaps (shown by 'dashed' lines) with that of the other having electron with opp..

A double covalent bond consists of two pairs of shared electrons. It is formed by the sharing of two pairs of electrons between two atoms. It is actually a combination of two single bonds. It is represented by putting two short lines between the two atoms [=..
