properties of giant covalent compounds

General Properties of Covalent Compounds - The main characteristic properties of covalent compounds a..

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. T..

Comparison of Properties of Electrovalent and Covalent Compounds Property Electrocalent or ionic compounds Covalent or molecular compounds Structure of charged ions They consist of oppositely charged molecule..

State of existence The covalent compounds do not exist as ions but exist as molecules. There are weak intermolecular forces between the molecules and hence they exist as liquids or gases at room temperature. However, a few compounds also exist in the solid..

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-atom..

Comparitively stronger forces than Van der Waal's forces exist between molecule..

The number of electrons, which an atom contributes towards mutual sharing during the formation of a chemical bond is called its covalency in that compound. Thus, the covalency of hydrogen in H 2 (H - H, H : H) Sometimes one or more pairs of electrons in the valen..

Characteristics of Covalent Compounds - 1) Covalent compounds consist of molecules and not ions. The molecules do not have any electric charge on them. The molecules are held together by weak forces called Van der Waal's forces . 2) Covalent co..

Covalent compounds are formed by the sharing of electrons by atoms of non-metallic elements between groups IVA and VIIA. The elements of these groups react with one another by sharing election pairs. Thus, the valency of an element in a covalent molecule is equal to th..

Lewis Structures of Some Covalent Compounds - The steps in writing Lewis structures of covalent compounds are as follows: of the molecule by placing the atoms of the combining elements properly. Usually an atom, which forms the largest number of bonds with ot..
