Depending what kind of leaves, most leaves contain mostly carbon, small traces of iron, potassium, and other metals (assuming they can be found in the soil).
By definition, organic compounds must contain hydrogen and carbon. Other common elements include oxygen and nitrogen and sometimes sulphur, phosphorus, halogens. There are many other compounds that contain metals (organometallic chemistry).
Alkali Metals
Steel always contains iron and carbon, and often contains cobalt, chromium, molybdenum, or other metals.
Metals can be found impure, when they are extracted from the earth's crust, where they may be combined with other chemical elements, in which case they may need to be chemically separated to make it the best for use.
Carbon is the only non-metal in carbon family. The other elements are either metalloids or metals.
Carbon
Depending what kind of leaves, most leaves contain mostly carbon, small traces of iron, potassium, and other metals (assuming they can be found in the soil).
Yes metals are found in rocks called ores. Most metals are more reactive and are found combined with other elements in rocks.
it depends. A lot of metals are elements like iron for example, these can be mixed to form alloys(compounds) steel for example is an aloy of carbon and iron. Metals exist as mixtures when they are found in their ores(mixed with other metals and minerals) and must be separated from their mixtures by smelting.
An alloy is a pure metal such as iron, this is mixed with other metals from the transition metals which can be found in between group 2 and 3 in the periodic table. Except in some cases like steel where a non-metal (in this case carbon) is added.
No, other elemental categories, such as alkali metals and transition metals are also found on the Earth's crust. One such alkali metal that is frequently found on the Earth's crust is potassium (K).
By definition, organic compounds must contain hydrogen and carbon. Other common elements include oxygen and nitrogen and sometimes sulphur, phosphorus, halogens. There are many other compounds that contain metals (organometallic chemistry).
Silver is found as free metal, or in minerals of other metals.
Alkali Metals
The primary metals in the core are iron and nickel with lesser amounts of other heavy metals.
In ordinary or "mild" steel, iron and carbon predominate. In stainless steel, there is usually a total of chromium and/or nickel that is substantially more than the carbon content. Molybdenum and some other metals are also found in some specialty steels.
