Answer

Thanku brother.... :-)

Answer

IONIC BOND :1.Ionic bond - Takes place between metals and non metals2.Ionic bond takes place by losing or gaining of electrons.3.Ionic bonds have higher  molecular strength between the molecules. 4.Ionic bonds have higher melting point and boiling point5.Ionic bonds are better conductors of electricity. COVALENT BOND :1.Covalent bonds takes place by sharing of electrons.2.Covalent bonds have lesser molecular strength between the molecules. 3.Covalent Bond - Takes place between non - metals. 4.Covalent bonds are poorer conductors of electricity. 5.Covalent bonds have lower melting point and boiling point.

Answer

Covalent Compounds:
Covalent compounds are formed when two or more non-metal atoms share electrons in order to achieve a stable electron configuration. In covalent bonding, the shared electrons are attracted to the positive nuclei of both atoms, resulting in the formation of a molecule. Let's explore the characteristics of covalent compounds in detail.

1. Bond Formation:
Covalent compounds are formed through the sharing of electrons between atoms. The atoms involved in the bond contribute one or more electrons to form a shared pair. This sharing allows both atoms to achieve a more stable electron configuration, usually resembling the nearest noble gas.

2. Molecular Structure:
Covalent compounds exist as discrete molecules held together by covalent bonds. The atoms within the molecule are arranged in a specific geometric arrangement, dictated by the number of shared electrons and the repulsion between electron pairs. This gives covalent compounds distinct shapes and bond angles.

3. Physical Properties:
Covalent compounds generally have lower melting and boiling points compared to ionic compounds. They are typically gases, liquids, or low-melting-point solids at room temperature, due to the weaker intermolecular forces between molecules. Covalent compounds also tend to be poor conductors of electricity, as they lack mobile ions or free electrons.

Ionic Compounds:
Ionic compounds are formed through the transfer of electrons between a metal and a non-metal atom. This transfer creates positively and negatively charged ions, which are attracted to each other through electrostatic forces. Let's delve into the characteristics of ionic compounds.

1. Bond Formation:
Ionic compounds are formed through the transfer of electrons from a metal atom (which tends to lose electrons and form positive ions) to a non-metal atom (which tends to gain electrons and form negative ions). The resulting electrostatic attraction between the oppositely charged ions forms the ionic bond.

2. Crystal Lattice Structure:
Ionic compounds exist as a repeating three-dimensional lattice structure, where each positive ion is surrounded by negative ions and vice versa. This regular arrangement maximizes the attractive forces between ions and provides stability to the compound.

3. Physical Properties:
Ionic compounds generally have high melting and boiling points due to the strong electrostatic forces between ions. They are typically solid at room temperature and form crystals. In the solid state, ionic compounds do not conduct electricity; however, when dissolved in water or molten, they dissociate into ions and can conduct electricity.

Conclusion:
In summary, covalent compounds are formed through the sharing of electrons between non-metal atoms and exist as discrete molecules, whereas ionic compounds are formed through the transfer of electrons between a metal and a non-metal atom and exist as a crystal lattice structure. Covalent compounds have lower melting and boiling points, are typically poor conductors of electricity, and have distinct molecular structures. Ionic compounds have high melting and boiling points, form crystals, and can conduct electricity when dissolved in water or molten.

Answer

Ionic compounds are formed by the transference of electrons just like NACl,MgCl2 where as covalent compounds are formed by the sharing of electrons just like hydrocarbons.
