Platinum usually exists uncombined in nature or alloyed with iridium.
No, different compounds found together but not chemically combined do not make up an element. An element is defined as a pure substance that consists of only one type of atom, characterized by its atomic number. Compounds are formed from two or more elements that are chemically bonded together. Therefore, a mixture of compounds does not change the fundamental nature of the individual elements present.
Hydrogen is found both free and chemically combined in nature. It is the most abundant element in the universe and is typically found combined with other elements such as oxygen in water or carbon in hydrocarbons. However, pure hydrogen gas can also be found in certain environments, such as in the atmospheres of gas giants like Jupiter and Saturn.
Platinum is an element, not a mixture or compound. It is a rare and valuable metal that is found in its pure form in nature and consists of only platinum atoms.
Mercury is a natural element. It is not man made or combined in nature. It is not a compound.
Mercury is an element, represented by the symbol Hg on the periodic table. It is a metal that is found in nature as a pure substance and does not need to be chemically combined with other elements to exist.
Yes. Platinum is a naturally occurring element, with atomic number 78.
The pale yellow element that occurs widely in nature in several free and combined allotropic forms is sulfur.
A free element refers to an element that exists in nature in its pure form without being combined with other elements. These elements are often found in the Earth's crust and can be easily isolated without the need for chemical reactions. Examples of free elements include gold, silver, and oxygen.
magnesium :)
Platinum is an elemental, metallic mineral.
Sulfur is not a highly reactive element under ordinary condition.
Plutonium exist in extremely low concentrations in uranium minerals; the chemical form is probably plutonium dioxide or a complex oxide with uranium.
