It is not a metal. It tends to get shorter when heated.
Yes, diamond and graphite are isotopes of carbon as they are both entirely made of carbon. However they have very different structures resulting in their different properties.
"Organic" materials are defined as materials that contain the element carbon, but a broader interpretation will include all of the CHON elements; Carbon, Hydrogen, Oxygen, and Nitrogen. Any substance that contains all four elements is certainly an "organic" molecule, even if it formed in the absence of any life process.
Burning fossil fuels (coal, oil and natural gas) are the bad ways to generate electricity, because they add long-hidden carbon dioxide, a greenhouse gas, into the atmosphere, causing global warming and climate change.Burning biofuels, (biomass, biodiesel etc) are neutral. They release carbon dioxide when burnt, but that carbon was recently removed from the atmosphere when the plants were grown, so biofuel is carbon-neutral.Solar, wind, hydroelectric, wave, tidal, geothermal and any other renewable energy are the good ways to generate electricity, as they have no carbon emissions.Nuclear power plants are another emission-free method of generating electricity. Nuclear does not contribute to global warming, but many people are afraid of nuclear accidents, and there is a problem of safely containing the remaining nuclear matter.
Diamonds are an allotropic form of carbon; they are materials having some properties, not property. Which is the scientific word for it. By Hayley
Strength:Carbon nanotubes are the strongest and stiffest materials yet discovered in terms of tensile strength and elastic modulus respectively.Hardness:Standard single-walled carbon nanotubes can withstand a pressure up to 25 GPa without deformation.
Graphite (an allotrope of carbon) and graphene does conduct electricity whilst other allotropes of carbon such as diamond do not.
Carbon (graphite) will conduct electricitySilicon metallic will conduct electricity
Yes the center carbon or lead can conduct electricity. The carbon in the pencil is also used in resistors for resistance in a circuit.
Carbon can conduct electricity reasonably well and is a non-metal.
yes
yes
Graphene, graphite, and some carbon nanotubes can all conduct electricity.
they don't conduct electricity: they have no free electrons. graphite, however, made of the same stuff as diamond (carbon) has a different structure, which means that it does have free electrons, and a lot of them. Therefore graphite is a good conductor of electricity.
carbon is not a metal and can conduct electricity
no
yes
currently there is no evidence of this.
