However, wet sand would conduct electricity because the water(not the sand) would allow the electrical current to pass through it. Metals have metallic bonding, so they have delocalised electrons free to move. It doesn't conduct a strong electrical current but it does conduct. Lv 6. Network compounds like NaCl and SiO2 have no movable "charges", and therefore will not easily conduct electricity in the solid state. Electricity requires a complete "loop" for current to flow. I've tried to look up salt atoms, but cannot for the life of me find any good source material, so I decided to ask all you smarties out there: Is salt a good conductor of electricity? If the sand has lots of ferro-magnesium minerals the conductiveity increased. Yes both are indeed covalent. According to this experiment, you could even say, H2O does a really bad job in conducting electricity. Turbidite. If NaCl is melted, then it will dissociate into ions which are movable, and so molten NaCl is a conductor. Of course, when NaCl is dissolved in water it dissociates into ions and will conduct electricity. Yes, H2O does conduct electricity but it does it very poorly. they all conduct electricity to some degree, some more than others, as a perfect insulator doesn't exist. Graphite, a covalent network compound, also has delocalised electrons. the resistivity data for silicon is widely available. Pure silica sand that is try is a poor conductor. Conclusion: Does Silicon Conduct Electricity? SiO2 is a giant covalent molecule and is insoluble in water, like Al2O3. This is called a closed circuit. It is a metalloid, also known as a semi-conductor. Distilled water has a very low ion count and therefore very little ability to promote electron movement. 1 decade ago. To conduct electricity a substance needs charged particles free to move. Check the source link for a neat experiment. Ionic compounds conduct when molten or in solution because the ions break free from the crystal lattice and can move. At zero degree temperature, it acts as an insulator because no free electrons are present that can move across the lattice to conduct electricity. Silicon is a semiconductor and it can act as a conductor and insulator both under different conditions. on the order of Kohm x m, vs. nohm x m for copper. Depends what the sand is made of and what is in it. 0 0. Salt water conducts electricity better than fresh water, or so I've heard. that should give you some sense of its conductivity. This would mean it has metallic bonds. Yes, Silicon does conduct electricity. Hence it cannot conduct electricity because it does not have freely-moving ions. On the Periodic Table of Elements, salt is considered a metal.
