why covalent bonds are directional

The sharing of orbitals between two atoms is possible only when the atoms are close enough to overlap their orbitals. Thus, orbital overlap is necessary for the sharing of electrons and bond formation. With the orbitals coming close together, there is an increase in the electron den..

Bonding in Covalent Solids - In covalent solids, the constituent particles are atoms of same or different kinds. Covalent bonds network, forming a continuous giant interlocking structure of atoms throughout the crystal that hold them together. They ..

Covalent bonds are formed by the overlap of atomic orbitals. As orbitals have different shapes, it is difficult to represent the actual shape of the orbitals on the paper. Hence a pictorial notation is adopted with the following rules: An orbital is represented by a square bo..

Although the Lewis structures give an idea of the valence electrons around the atom, in reality it does not precisely locate the position of the electrons in the chemical bond. The behaviour of electrons in molecules and compounds is made by the valence bond theory in terms of t..

Since the covalent bond is localised in between nuclei of atoms, it is directional in natur..

Covalent Bonding - When the combining atoms have 4, 5, 6, or 7 electrons in the outermost or valence shell, they cannot donate electrons. Instead, they mutually share electrons in order to complete their octet in the outermost orbit or shell. Such a type of valency is referred t..

A covalent bond is defined 'as the force of attraction arising due to mutual sharing of electrons between the two atoms'. The combining atoms may share one, two or three pairs of electrons. The covalent bond is formed between two similar or dissimilar atoms b..

Can we imagine a world without oxygen, nitrogen, water or carbon dioxide? Without any of these there would be no life at all. All the above mentioned compounds are covalent compounds formed by sharing of electrons. Non-metal atoms share the valence electrons and form molecules. These shar..
