Why do solid and liquid metals conduct electricity?
Graphite, an allotrope of carbon, is classified as a semimetal, that is, a material that shares some of the properties of metals. Many other non-metallic materials conduct electricity; including salts, plasma and some polymers.
Is carbon solid liquid or gas?
Carbon can exist in all three states of matter - solid, liquid, and gas. At room temperature and pressure, carbon commonly exists as a solid in the form of graphite or diamond. Carbon can also be found in the gaseous state in the form of carbon dioxide, and under extreme conditions, it can melt into a liquid state.
Is carbon a gas liquid or solid?
Carbon can exist as a solid, liquid, or gas, depending on its form. Graphite and diamond are solid forms of carbon, while carbon dioxide is a gas, and liquid carbon can exist in supercritical conditions.
Is carbon gas solid liquid?
Carbon is a solid at room temperature.
Is carbon a liquid solid or gas?
if you mean carbondioxide, then it's state is meant to me gas.Answeri think carbon i s gasAnswerthe people above me are fails, carbon is a solid and is a nonmetal. it is able to form strong covalent bond with other carbon hence gives it a high melting point. common carbon is graphite and diamond.
What minerals are in pencil lead?
Only Carbon - Graphite Its a covalent solid the only one that can conduct electricity
Does graphite conduct electricity?
It in-fact does conduct electricity, molten graphite is a key element in which terrorists use for I.E.D'S it causes a large heat blast when heated with electricity and mixed with different compounds.
Does pencil lead conduct electricity?
Pencil lead (aka graphite) DOES conduct electricity. It does this thanks to electron delocalization within the carbon layers. Since the valence electrons are free to move, they are able to conduct electricity.
Does carbon tetrachloride conduct electricity when a solid?
No, carbon tetrachloride does not conduct electricity as a solid because it is a nonpolar molecule, meaning it lacks charged particles. In order to conduct electricity, a substance needs to have charged particles that can move to carry the electric current.
Why graphite a nonmetal?
Graphite is a form of the element carbon, which is a nonmetal. While it has a metallic luster and conducts electricity, graphite is brittle. Unlike metals, which are held together by metallic bonds, graphite is a covalent network solid. Other forms of carbon behave more clearly as nonmetals.
What does this solid carbon become part of?
Solid carbon (C) may be diamond, graphite, coal, carbon black etc.
What is graphite solid liquid or gas?
Graphite is a solid form of carbon. It is a crystalline form of carbon where the carbon atoms are arranged in layers. Graphite has a high melting point and does not exist in a liquid or gaseous state under normal conditions.
Is graphite a noble gas?
Nope.... graphite is a solid - a form of carbon.
Diamonds and graphite are examples of what solid?
Diamonds and graphite are both allotropes of carbon.
Why do solid and liquid metals conduct electricity?
Graphite, an allotrope of carbon, is classified as a semimetal, that is, a material that shares some of the properties of metals. Many other non-metallic materials conduct electricity; including salts, plasma and some polymers.
What state is carbon (graphite) at 20 degrees celsius?
Graphite is a solid at 20 0C.
How can different forms of a solid have different clarities like graphite and diamond?
Although graphite and diamond are both formed from carbon, the physical structure of the electrons for each is different from the other. Diamond atoms are packed more tightly than are atoms in any other mineral, making them (more or less) clear -- there is no response to external stimulus, such as electricity that 'moves' the atoms. Graphite atoms are structured differently, allowing electrons to move: graphite conducts electricity. This makes graphite not clear. Here's a more technical explanation from Wikipedia: "Graphite is able to conduct electricity, due to delocalization of the pi bond electrons above and below the planes of the carbon atoms. These electrons are free to move, so are able to conduct electricity. However, the electricity is only conducted along the plane of the layers. In diamond, all four outer electrons of each carbon atom are 'localised' between the atoms in covalent bonding. The movement of electrons is restricted and diamond does not conduct an electric current. In graphite, each carbon atom uses only 3 of its 4 outer energy level electrons in covalently bonding to three other carbon atoms in a plane. Each carbon atom contributes one electron to a delocalised system of electrons that is also a part of the chemical bonding. The delocalised electrons are free to move throughout the plane. For this reason, graphite conducts electricity along the planes of carbon atoms, but does not conduct in a direction at right angles to the plane."
