What property makes metal a good conductor and rubber a good insulator?Question:What property makes metal a good conductor and rubber a good insulator?Crystal Lattice:A crystal lattice is an ordered three-dimensional arrangement of atoms, ions, or molecules of a material that forms th...
That’s because metal is a great conductor of electricity. (In fact, so is the human body, which is why you can sometimes pass the shock on to someone else.) The opposite of a conductor is an insulator, which impedes the flow of electrons from one material to another. Rubber is a gr...
Carbon is a non-metal and therefore has covalent bonds. However, in this experiment, it exhibited metallic properties. Carbon in the form of graphite is the only non-metallic element that conducts electricity. As we all know,graphiteis composed of sheets of hexagons of carbon atoms joined by...
It is one of the better hobbyist grade tumblers, and it tumbles about ten pounds of rock. It has a metal barrel with a rubber liner. Many Model B rock tumblers have been in reliable use for decades. Common opal: Pictured here several varieties of common opal that include pink opal from...
Can you put rubber in recycle bin? You probably already know that glass, metal, and paper are recyclable, but what about toothbrushes, rubber bands, and old computers? These items don't really fall into standard recycling categories and aren't in your neighborhood recycling guide. Is rubber ...
What's the strongest type of metal? Describe what the property of a substance is and give some examples. Describe what are the properties of matter? What property makes metal a good conductor and rubber a good insulator? What are four chemical and physical properties of elements?
of electrons, thus leading to high electricalcurrent. Typically, metals, metal alloys, electrolytes and even some nonmetals, like graphite and liquids, are good electrical conductors. Pure elemental silver is one of the best electrical conductors. Other good electrical conductors include the following...
