mechanical properties and electrical properties of covalent bonding

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..

Properties of Covalent Compounds - The covalent compounds do not exist as ions but they exist as molecules They exist at room temperature, as liquids or gases. However, a few compounds also exist in the solid state e.g. urea, sugar, etc. The melting and boiling points ..

A covalent bond can be formed in different ways. When a bond is formed by mutual sharing of one pair of electrons it is known as a 'single covalent bond', or simply 'a single bond..

Property Electrovalent or ionic compounds Covalent or molecular compounds Structure of charged ions They consist of oppositely charged molecules They consist of uncharged or neutral molecules Physical state and hardness The inter-atomic attraction is hig..

Molecular hydrides are soft. They are generally, volatile in nature and have low melting and boiling points. They have low electrical conductivity. The electronegativity difference between hydrogen and the atom bonded to it, determines the properties of ..

Ceramics are: Lighter, stiffer and corrosion resistant. They are brittle because of strong directional bonds. So they shatter rather than deform. The electrons in ceramics are tightly held because of covalent bonds. There are no mobile electrons to conduct curren..

More than 80 elements in the periodic table are metals. Metals are solids at ordinary temperature and pressure, with the exception (of mercury and gallium). Metals have characteristic properties such as: High thermal and electrical conductivity. Luster and high reflectivity. Mal..

Saturated Organic Compounds Unsaturated Organic Compounds These organic compounds contain single carbon-carbon covalent bond. These organic compounds contain at least one double or triple covalent bond. Due to the presence of all single h..

Travel in straight lines: They cast a shadow of the objects placed in their way. Produce mechanical effect: A paddle wheel placed in their path starts rotating. Rays are positively charged: Anode rays are deflected towards the negative plate of an electric field. The ..
