Answer 1

Electricity is moving electrons around. If the electrons can move more freely there is more conductivity.

In the case of most metals, you have the metallic bond, where there’s a cloud of electrons floating around the metal (iron, silver, copper) atoms, making the electron movement way easier than in a non-metallic element.
