AbstractValence bond theory (VBT) was developed by Linus Paulin. It assumes that the metal-ligand bonds are formed by donating an electron pair by the ligand to the metal and thus form a coordinate bond between the metal and ligand. Economic, social, and political sharing creates a strong bond between Nairobi city and the three county towns of Kiambu, Machakos, and Kajiado. In the modern dispensation, agglomeration of neighboring urban centers and their adjacent rural areas are transforming into regional economic development areas guided by political outline.
