formation of molecules

An atom having a charge on it is called an ion. When an atom loses or gains charge, it gets converted into a positively or negatively charged ion respectivel..

Formation 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 belo..

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 ..

Sometimes, two or more stable molecules combine to form a molecular complex. In a complex molecule, the constituent molecules are held together by a 'coordinate bond'. One typical example involves the molecules of NH 3 and BF 3 . The electron dot structures..

Nitrogen atom has five electrons in its valence shell. Thus, it requires three more electrons to acquire a stable configuration of the nearest noble gas (neon). This is done by mutually sharing three pairs of electrons as shown below: ..

Atoms and Molecules - Formation of Molecule Atoms of most of the elements do not exist independently. They either form molecules or ions. An atom having a charge on it is called an ion. When an atom loses or gains charge, it gets converted into a positively o..

We have learnt that the electrons in bonding molecular orbitals contribute to attraction between the atoms and thereby help in the formation of bond. On the other hand the electrons in antibonding molecular orbitals contribute to repulsion between the atoms and, therefore oppose the ..
