what is difference between covalent,metallic,and ionic bonding ?give difference with example
Answers
Answer:
1.Covalent bonds can be said when there is the strong electrostatic force of attractions between two positively charged nuclei and the shared pair of electrons. While metallic bonds have the strong electrostatic force of attractions between the cation or atoms and the delocalized electrons in the geometrical arrangement of the two metals. When there is the strong electrostatic force of attraction between a cation and an anion (two oppositely charged ions) of elements is called ionic bond and is formed between a metal and a non-metal.
2.Covalent bond exists as solids, liquids and gasses, metallic bonds and ionic bonds exist in the solid state only.
3.Covalent bonds occur between two non-metals, metallic bonds is between two metals, while ionic is observed between non-metal and metal.
4.Covalent bonds involve sharing of electrons in the valence shell, metallic bonds are the attraction between the delocalized electrons present in the lattice of the metals, and ionic bonds are referred as the transferring and accepting of electrons from the valence shell.
5.Conductivity is low in covalent and ionic bonds, though high in metallic bonds.
6.Covalent bonds are not very hard, though exceptions are silicon, diamond, and carbon, even the metallic bonds are not hard, but ionic bonds are hard, because of the crystalline nature.
7.Melting and boiling points of the covalent bond are low unlike the metallic bonds and ionic bonds which have higher.
8.Metallic bonds are malleable and ductile, while covalent bonds and ionic bonds non-malleable and non-ductile.
9.Bond energy is higher in covalent and ionic bonds than the metallic bonds.
10.Examples of covalent bonds are diamond, carbon, silica, hydrogen gas, water, nitrogen gas, etc., whereas Silver, gold, nickel, copper, iron, etc. are examples of the metallic bonds and NaCl, BeO, LiF, etc. are the examples of the ionic bonds.

Explanation:
BASIS FOR COMPARISON COVALENT BOND, METALLIC BOND ,IONIC BOND
Meaning
When there is a strong electrostatic force of attractions between two positively charged nuclei and the shared pair of electrons is called the covalent bond.
When there is the strong electrostatic force of attractions between the cation or atoms and the delocalized electrons in the geometrical arrangement of the two metals, is called a metallic bond.
When there is a strong electrostatic force of attraction between a cation and an anion (two oppositely charged ions) of elements is called the ionic bond. This bond is formed between a metal and a non-metal.
Examples:Diamond, carbon, silica, hydrogen gas, water, nitrogen gas, etc.
Examples: Silver, gold, nickel, copper, iron, etc.
Examples:NaCl, BeO, LiF, etc.
hope it helps....
