Platinum is usually found pure.
Boron is typically found in nature as a compound rather than in pure elemental form. Examples include borax, boric acid, and various borates.
Titanium is typically found in compound form, such as titanium dioxide, rather than in pure elemental form. It is commonly extracted from minerals like ilmenite and rutile, and then processed to obtain pure titanium metal.
It can be found in both compound and pure forms. In nature, elements are often found in compounds, while in labs, they can be isolated and purified into their elemental form.
Calcium is usually found in compounds rather than as a pure element. Common calcium compounds include calcium carbonate (found in limestone and eggshells) and calcium hydroxide (used in cement and as a food additive).
Gold and platinum are found as pure metals because they are very unreactive and resistant to corrosion. This allows them to exist in nature in a relatively pure form without reacting with other elements. Additionally, their chemical properties make them highly resistant to oxidation and weathering, further contributing to their presence as pure metals.
Platinum is an element, so it is "pure".
In pure form.
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.
Boron is typically found in nature as a compound rather than in pure elemental form. Examples include borax, boric acid, and various borates.
Technetium is found in both in a compound and pure forms
Titanium is typically found in compound form, such as titanium dioxide, rather than in pure elemental form. It is commonly extracted from minerals like ilmenite and rutile, and then processed to obtain pure titanium metal.
Silver is typically found in nature in the form of compounds, such as silver sulfide or silver chloride. However, it can also be found in its pure elemental form, especially when it occurs as native silver in deposits of ore.
Californium is a pure element.
It can be found in both compound and pure forms. In nature, elements are often found in compounds, while in labs, they can be isolated and purified into their elemental form.
Both. Iron can be found by itself as a pure element, or it can be found in many compounds such as iron chloride, iron oxide, etc.
Because Platinum is very inert and thus is found in native state.
Calcium is usually found in compounds rather than as a pure element. Common calcium compounds include calcium carbonate (found in limestone and eggshells) and calcium hydroxide (used in cement and as a food additive).
