No, silicon is not a better conductor of electric current than silver. In fact, silver is the best conductor of electricity among all metals.

Here's why:

* Silver has a very high electrical conductivity due to its free electrons, which can easily move and carry electric current.

* Silicon is a semiconductor, meaning its conductivity falls somewhere between that of a conductor and an insulator. It's used in electronic devices because its conductivity can be controlled, but it's not nearly as good at conducting electricity as silver.

In summary: Silver is a far superior conductor of electricity compared to silicon.
