But their chemical symbols are different, so they are different elements, different substances, but they feel the same thing... Tangled up ~!
One kind is metal, one kind is nonmetal, the property is not lively, the property is stable,
No one is the same. Lead is poisonous, and pencil lead is lead. The structure of carbon is the same as that of diamonds. Generally speaking, they are of structure, density and composition. No one is the same
The difference is that one of the similarities is that the appearance is black. However, the lead section is metallic luster. Carbon density is very small, about 2G per cubic centimeter, lead density is great, the density is more than 10g per cubic centimeter. Carbon is a nonmetal that can be converted into diamond. Lead is a kind of metal. Carbon is a chemically stable substance at normal temperature. Without poison, activated carbon can be used as a gas mask. Lead is a heavy metal that is harmful to humans. The chemical properties are more lively and can be used as lead batteries. The melting point of lead is very low, only a few Baidu, and the melting point of carbon can reach more than 3000 degrees. Edison made the filament out of carbon. You know that?.
