Both.
Platinum usually exists uncombined in nature or alloyed with iridium.
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.
Sulfur
Sulfur is a pale yellow element that occurs widely in several free and combined allotropic forms, such as rhombic sulfur and monoclinic sulfur. These different forms exhibit variations in properties such as color, density, and stability.
The element you are referring to is sulfur. It is a non-metal that is commonly found in nature in various forms, such as pure elemental sulfur, sulfides, and sulfates. Sulfur is known for its pale yellow color and distinctive odor.
Plutonium exist in extremely low concentrations in uranium minerals; the chemical form is probably plutonium dioxide or a complex oxide with uranium.
The pale yellow element that occurs widely in nature in several free and combined allotropic forms is sulfur.
Free nitrogen means chemically free, it has not combined with any other elements. Fixed nitrogen has combined to make ammonium compounds or nitrate compounds which can be easily absorbed by plants and used to make amino acids in the plant cells.
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.
There's not much oxygen on any planet except Earth. I mean "free" oxygen, not chemically combined with other elements. Obviously carbon dioxide contains oxygen combined with carbon, for example.
Argon is found in the Earth's atmosphere, where it exists as a free element. It is also commonly found in combination with other elements in minerals such as feldspar, micas, and zeolites.
Not all foundations contain sulfur. However, some foundations do contain sulfur as an ingredient, so it is important to check the product label or consult with a dermatologist to find sulfur-free options that are safe for you to use.
