Change in electrical conductivity when going down group 14 is _________.

• Increases, because the atomic radius causes the valence electrons to become more delocalised.
• Increases, the size of atom is increasing, the attractive force between the atom will decrease.
• Increases, the atomic radius causes the valence electrons to become more delocalised.
• Increases, the atomic forces within the larger molecules are strong.
