If true enter 1, else enter 0.
Although both carbon and silicon are in group IVA(14), very few Si - Si bonds are known.

Answer 1

Although both carbon and silicon are in group IVA(14), very few Si-Si bonds are known. This is because of larger size of silicon (Si) results in poor sideway overlap of $p$ -orbitals to form $\pi$-bond as compared to cabon atoms.
