Physical and chemical properties
Melting point - 839° C
Boiling point - 1484° C
Density - 1.54 g/cm3
Appearance - Calcium is dull gray, but it is shiny when scratched.
Other physical properties - Calcium is an excellent conductor of electricity. It is very soft and easily scratched.
Chemical properties - Calcium reacts rapidly with air to form a coating of gray oxide, and it burns with a red flame.
Compounds - Compounds of calcium are white in color. One compound is calcium carbonate, which makes up limestone (used in cement manufacture).
Melting point - 3550° C
Boiling point - 4827° C
Density - 1.9 g/cm³ (charcoal); 2.3 g/cm³ (graphite, or carbon rod); 3.5 g/cm³ (diamond).
1.9 g/cm³ (charcoal); 2.3 g/cm³ (graphite, or carbon rod); 3.5 g/cm³ (diamond).
Other physical properties - There are three forms of carbon: charcoal, graphite, and diamond (which is the hardest substance known). Each form has different physical properties.
Chemical properties - Carbon combines with oxygen in the air to form carbon dioxide.
Compunds - Carbon forms a wide variety of compounds, many of which are important components in living things. It is present in the compounds found in coal and limestone.
Uses - Charcoal is used in filters to absorb impurities in water or smells from the air. It is also used as a fuel for cooking (for example, in barbeques). Graphite is used as a lubricant and to make pencil leads. Diamond is used in jewelry and in cutting tools (because of its hardness)
