The stability of C-C, N-N, and O-O bonds compared to Si-Si, P-P, and S-S bonds is attributed to the ability of the former elements to form strong pi bonds. Elements like carbon, nitrogen, and oxygen can effectively overlap their p orbitals to form pi bonds, which are crucial for the stability of double and triple bonds. In contrast, elements like silicon, phosphorus, and sulfur have larger atomic sizes and their p orbitals do not overlap as effectively, making their pi bonds weaker and their single bonds less stable.
