Gold like many other elemental metals is found in ores rather than in its pure state and must be refined before ingots of the metal can be produced
Oxides are the type of compound that is typically formed when an element is burned in air. Oxides are compounds composed of an element combined with oxygen.
The charge of an ion formed by an element on the periodic table is determined by the number of electrons gained or lost by the element. This charge can be positive or negative, depending on whether the element loses or gains electrons.
The extent to which reacting ions are removed from solution depends on the solubility product constant of the compound formed and the initial concentrations of reactants in the solution. A higher solubility product constant indicates greater tendency to form a precipitate, while higher initial concentrations of reactants can shift the equilibrium towards more product formation and precipitation.
Rust is most of all 'metal oxide' which is chemically formed by reaction of certain metals (not all) with oxygen (gas, 20% in air)
C12 is an isotope of the element carbon. It is not a compound since compounds are formed when two or more different elements chemically combine.
Yes , it is an element. It is formed naturally and found in various concentrations ranging from pure"veins" to ore's laden with differing concentrations.
The gaseous element "radon".
Melanin
Shale
1. As a natural element francium exist in infinitesimal concentrations in uranium ores (as a progeny of 235U in the decay chain). 2. Francium can be also obtained by nuclear reactions: 197Au + 18O----------210Fr + 5 n
A non element. Steel is formed from Iron and carbon.
Hydrogen. It is also the lightest element and the first element that ever formed.
these "formed elements" are called the organelles.
Carbon
uranium

The element is carbon.
