Elements are examples of pure substances. Lead is an element, which means lead is pure.
Silver is most commonly found as its oxide in their ores.
Pure phosphorus is extracted my chemical means and can be bought, but it does not occur in nature.
Actually there are lots of elements which are commonly found only in compounds rather than in their pure elemental form. Sodium, magnesium, calcium, hydrogen come immediately to mind, but there are lots more.
Sulfur is found both "pure" (elemental Sulfur)or as an ore(sulfur compounds). It occurs commonly in either form.
Elements are examples of pure substances. Lead is an element, which means lead is pure.
In pure form.
Lead is an element. But both an elements and compounds are pure substances.
Usually it is found in compound form but can easily as a pure element, just depends on the conditions
I think its pure. Its found in the periodic table. cheers
Technetium is found in both in a compound and pure forms
Lead is an element and is natural, but is not often found in its pure state. It is usually found in an ore that has a lead compound and a mixture of other compounds of other metals. It is then refined to produce more pure lead metal.
Gold
Pure rhenium is silvery white, but it is not found naturally in its pure form.
yes but not in it's pure form
Helium has completely filled orbitals. hence it is chemically inert (non reactive) and is found in its pure elemental form.
Gold and platinum can be found in pure form in the crust - although thousands of years of diligent searching has already found everything that is easily found.
