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