Why are the noble gases chemically inert?

The outer or valence shell of these elements is complete. And they need not to make any bond. They do not share or transfer the electrons . Due to fully filled orbitals, Their ionisation enthalpies are also very high. So removing an electron from them is also very difficult. The examples of these are Helium, Neon, Argon, Krypton , Xenon […]

Why the chemical bonding takes place?

Kossel and Lewis in 1916 Developed the theory for the bond formation after watching the behavior of noble gases. The noble gases were inert in behavior and do not react with any substance. Kossel and Lewis found that the Octateof noble gases was complete so they do not react. They gave the theory that the elements react with other elements […]

Why does a covalent bond not form a crystal lattice?

Covalent bond and ionic bond has a very basic difference that is presence of ions or not. The ionic bonds are not limited to one ion only, actually they keep on joining again and again because they are held together by basically the electrostatic forces, due to the oppositely charged ions. lets take example of NaCl molecule. The positively charged […]
