Question

Why are silicon-silicon bonds weak?

Answer 1

hloo frnd and your answer is as follows.......

silicon- silicon bonds are weak because the electrons in the bonding region are farther from the two nuclei the energy gain they obtain from being in the bond is less, so the bond is weaker. 

hope it helps u.....☺☺

Answer 2

Why are silicon-silicon bonds weak?

If carbon–carbon bonds are reasonably strong and silicon and carbon are both in the same column of the periodic table meaning they have the same amount of valence electrons, also seeing as its bonding with itself electronegativity isn't an issue,
