CHEMICAL BONDING AND MOLECULAR STRUCTURE
The force which binds atoms together in a molecule is called a chemical bond. Bond formation is always an energy releasing process i.e., an exothermic process. It is shown in the graph below:

Figure 2.1
A + B are isolated atoms
A − B is molecule formed from A and B
r0 is bond length in A − B
E is bond energy
Different types of chemical bonds
- Strong bonds
- Ionic (or Electrovalent) bond
- Covalent bond
- Coordinate covalent bond.
- Metallic bond
Metallic bond strength ranges from very weak (in alkali metals) to very strong (in transition metals.).
- In addition to ...
